A very usful, practical (and good) book except that.......
I bought this book a while ago but didn't really read it (it cost me a lot to buy this book). I almost sold this book two years ago but nobody wanted to pick it up. How lucky I was!!! Recently I need to implement algorithms for a wireless Modem, and I need many tricks for such like sin(), cos(), arctan(), 1/x.... and I couldn't found other books talking about how to approximate those functions for real world application until I got this book from the basement, and suddenly I found this is the book that can show me those practical skill in the real world problem!!

This book talks about many wireless systems and subcircuits, and much more useful than other books is that this book show you how you can make the real circuit (Singal Processing) to approximate many fucntions used in those subcircuits.

However, this book has two weakness, first, some of the sentences are not easy to understand and second, it was written in 1994, it doesn't have up-to-date information and there are many advancement in todays digital radio.

Review of Modern Digital Signal Processing by R. Cristi
Professor Cristi's new book on modern DSP is a clear and concise treatment of contemporary DSP topics, such as multi-rate/multi-resolution, DFT filter banks, and time-frequency representations. Standard, easy-to-read notation combines with excellent figures and good practical examples make this book not only a good classroom text, but also a good reference for engineers and researchers alike. Especially well written are the chapters on multi-rate DSP and filterbanks, where Professor Cristi succeeds in unifying and simplifying important concepts rather than exhaustively decomposing them into mind-numbing detail as do the several classic texts on the subject. ...

very useful book
This is a very useful book when it comes to using the EVM board for writing and testing assembly and C algorithms on theTMS320C6000 DSP processor.It condenses a lot of information appearingin many TI manuals in an effective way toquickly learn how to use TMS320C6000. I have found this feature very usefulfor my type of research work in signal processing. digital signal processing.

Not for C6x starter
I'm just writing this to warn starters with C6x not to buy this book. It added nothing to TI documentation that can help me unwrap my SDK.

One Handy Book to have
I do a lot of programming on the C6000 series. This book is very helpful as a reference and saves you a lot of time. Best part is, you don't have to read it in sequence. You need a certain amount of C programming experience,but you probably already have that if you're using this processor. It has agood coverage of Code Composer and it has what you need to get you up andrunning quick. Definitely worth it in terms of sheer time saved inoptimizing programs. When you're through with this book, you have a betterunderstanding of the processor and an overall better picture onimplementing those algos you use so often. Good buy. Maybe not the best,but for the cost - excellent.

Not Readily Readable
Huy.
This book isnt too bad when trying to cover various different architechtures. However the way the suject is handled boggles my mind that I have started to fear this complex subject now!!

Any way...even other books like the one by Uwe Beyer is hard reading and u have to really scratch your gray cells a lot. I am still to come across a book with ample examples. Hence I am not giving this book a 'one star rating'
If any one does know such a book then please do write an online review that can help all novice to this field.

A book of high quality DSP architectures
As an experienced DSP engineer, I can say this is a very useful book. Pirsch quickly gets to the heart of the matter and presents practical high quality DSP architectures for implementation in ASICor FPGAs.

beyond horrible
ridiculous explanations of fundamental concepts.some chapter exercises are so damn confusing you'll spend a hell of a time wondering how to start.and nothing justifies the price of this useless little book!If you're assigned this book, best of luck

Worst book in DSP
This is the worst book I have ever used as a student. It not only is vague, but lacks samples to difficult concepts which makes it very difficult to follow.

Product Description
Digital Signal Processing (DSP), as the term suggests, is the processing of signals using digital computers. These signals might be anything transferred from an analog domain to a digital form (e.g., temperature and pressure sensors, voices over a telephone, images from a camera, or data transmittal though computers). As a result, understanding the whole spectrum of DSP technology can be a daunting task for electrical engineering professionals and students alike.

Digital Signal Processing Fundamentals provides a comprehensive look at DSP by introducing the important mathematical processes and then providing several application-specific tutorials for practicing the techniques learned. Beginning with general theory, including Fourier Analysis, the mathematics of complex numbers, Fourier transforms, differential equations, analog and digital filters, and much more; the book then delves into Matlab and Scilab tutorials with examples on solving practical engineering problems, followed by software applications on image processing and audio processing—complete with all the algorithms and source code. This is an invaluable resource for anyone seeking to understand how DSP works.

Features:
* Provides a comprehensive overview and introduction of digital signal processing technology
* Provides applications with software algorithms
* Explains the concept of Nyquist frequency, orthogonal functions, and method of finding Fourier coefficients
* Includes a CD-ROM with the source code for the projects plus Matlab and Scilab scripts that generate graphs, figures in the book, and third party application software
* Discusses the techniques of digital filtering and windowing of input data, including: Butterwoth, Chebyshev, and elliptic filter formulation

On the CD
The CD-ROM contains useful tutorials, source code from the text, and third-party software. (Please see Appendix D for details.)

SYSTEM REQUIREMENTS
To run all of the applications on this CD-ROM you will need a PC with 900MHz Pentium III processor or equivalent; WinXP, Linux (Red Hat 8.0 or later, or comparable Linux distribution); 128MB RAM; 2MB free hard disk space; CD-ROM drive; Grace v5.1.1.12; Perl v5.8.5; Perl/Tk module Tk-804.027; high resolution graphics card (see Appendix D for detailed requirements for running the Scilab and Matlab software). ...

A Decent Book But Has Odd Notational Inconsistencies
This book has a great outline with all of the classic treatments of the subject; Complex numbers, Digital Filters, Fourier analysis, etc. A solid foundation is set forth in early chapters in a mixed of theory and heuristic explanation to present to a wide range of experienced reader. The key issue I have between rating this book a full 5 stars is that of notational inconsistency and the rather poor synchronization of the text with the figures. There are several places where the author is referencing a figure and the reader is left wonder if the individual generating the figures discussed the figure with the author prior to publishing the book. For example, the discussion of phasors includes a graph of a sine wave with a peak magnitude of 1. The accompanying equation mysteriously has the value 10sin(...). This seems minor at first glance yet there other examples of an apparent disconnect between text and associated figures. Some of the equations referenced appear unchecked. For example, i(t) = Re{10exp(j*w*t + phi)} = Re{10exp(j*2*pi*t)} = Re{10*exp(j*phi)} (Reviewer note: f =1 in this equation and omission of f was acceptable)?

In summary, the book is good but could have been better proof read prior to publication; in this reviewer's opinion.

Solid Theory, Lots of Software
Digital Signal processing has changed tremendously in recent years. The advent of ever higher performance processors have all but elminimated using analog circuits to process analog signals. Both the faster CPUs, and the advent of specialized single instruction multiple data (SIMD) instructions have made digital signal processing much easier. Combining the new instructions with specialized software (included on the enclosed CD, including MatLab and SciLab) has completely changed the nature of signal processing.

This book starts with a solid mathematical foundation before going on to more practical applications. It is not a For Dummies book, the mathematics is certainly college level.

new view about trading
I've read lots of books on trading, all of them using the balance between the bulls and the bears, their psicology, who's stronger and how this affects the market. Some of these books are absolutely genial.
This book gives a completely new view about the market. At least new to me. Interpreting the market as a signal (just as if it were radio signal, or whatever) and processing the results gives surprising results. In some cases these results are not very different from the traditional indicators, but in others results are incredible. In any case the arsenal of new tools opens possibilities to increase the effectiveness of trading and you can choose which tools fit your trading. You can find at least one, for sure. Well, at least I found some.
No panacea here. No miracles. But interesting and effective new point of view and tools.

Not bad
If I could, I'd give this 3 1/2 stars.

In general a pretty good book.The big thing that drags it down is that Mr. Ehlers starts using some very technical DSP terms right away without giving any type of definition or explanation.Therefore, those who are familiar with that field will benefit most, while those of us outside it are left to muddle through.Still, a reasonably intelligent person should be able to get most of what he's saying, with some work.

Either incomprehensible or you've outgrown it
Fine book for what it is, but this is just not the right technique for systematic trading because the models proposed are misspecified for the signal over the time series (as another reviewer pointed out, price time series do not conform to the conditions of electrical and telecommunications signals).

Still, many of the skills needed to isolate real signals and deploy real strategies are built through exercising with these methods, so all is not lost if you wade through this, deploy something, and come back with knowledge but little cash.

Who is the book not for: phynance-lite Excel-based users.

Who is the book for? Do you use Matlab or Mathematica or Maple? Do you know what an Active X link is for data feeds? Do you look at the tick data of the currency and swaps market and see gold? Are you laughing at me because these questions are inefficient baby-level stuff? (Hint: you've outgrown this book).

Just Great
I think this book is great even for non-math people. In fact, I am not good at math at all. I read it a couple of times and figured out what the author wanted to say.

This book is especially good for people who are interested in creating their own trading systems.

A Balanced Review
Whoever reads the reviews for this book will note the polarity: people either think it's wonderful or it's horrid. I'll try to give a more balanced review here.

* This book is for the mathematically/analytically inclined. If you don't consider yourself in this category, I would not suggest this book. At the VERY least you should have a solid background in trigonometry.

* This book is exactly what is says: Digital-Signal Processing (DSP) applied to stock trading. I myself am an Electrical Engineer who's day-job consists of about 90% DSP-work / 10% other tasks. For this reason, I believe I can fairly say that the DSP concepts presented are done so in a fairly clear and fairly accurate manner (this varies from time-to-time).

* Most of the concepts presented in Ehlers' book would be what I consider "traditional" DSP. There is a problem here (that is almost completely overlooked in the book): "Traditional" DSP is based on a series of assumptions that must be at least approximately fulfilled. Recent academic research has tended to show that stock-market "signals" tend NOT to fulfill these assumptions very well. In some ways, this puts a significant dent (in my view) in the theory used as the basis for the indicators derived.

* The attention to detail at times is very obtrusive to a reader with a keen eye and understanding of what is being described. For example: there is (what I consider to be) a glaring error in the MAMA filter that no one has ever pointed out and that is not corrected on his website. How has this escaped notice for so long? [Side note: be careful about his claim that MAMA's avoid whipsaws - they DON'T at all in ranging markets!]

* Two mechanical systems are described in detail in the book: the SineTrend Automatic System and the ZeroLag Intraday System. I have EXTENSIVELY tested both systems, exactly as described in the book, on a very-wide range of stocks, commodities, and currencies. These simulations were carried out using a test suite I had developed for my own use to simulate trading conditions as realistically as possible. This includes conservative, but realistic allowances for slippage, commissions ($15 round-turn), and signal reaction.

Ehlers results for the SineTrend Automatic System grab your attention in the book (greater than $100,000). However, no initial investment is listed in the book and one should be careful to note that these results are over a 15 year period. Assuming a $10000 initial investment (though this isn't specified in the book), this is a 17% annual return. Not bad, not great.

The REAL problem here is that a more realistic simulation shows that one is hard-pressed to show ANY profit on ANY type of stock/commodity/currency.I've tried the system (unaltered) on dozens of instruments, with a couple rather moderate successes and the rest losing money terribly, even with reasonable stop losses and money management.

* Almost (if not all) of Ehler's graphs in his book are from the same time series: specifically the US96H (March 1996 Treasury Bond contracts). I HAVE been able to reproduce all of the graphs in his book using the indicators: so there is no falsification in them, as implied in other reviews. However, the time period under consideration shows a series with nearly ideal characteristics for Ehlers systems, while almost all other series I've tested his indicators and systems on do not exhibit the same performance.

* MOST ALL of the information presented in his book is available for FREE download on his website as Word DOCs. There is also a lot of other papers he has written available on the site.

* Ehlers is doing what I think needs to be done in the trading industry: trying new techniques and methods. He has a good grasp of the electrical-engineering concepts and how to apply them to trading, but the results presented in his book are NOT indicative of TYPICAL results of the performance of his systems. The ideas and the theory behind them are, generally, good, though he is a bit prone in parts to handwaving and glossing-over of some obvious pitfalls (obvious, at least, to another electrical engineer).

* For the mathematically-inclined who enjoy working on their own ideas and own systems, this book could give you a lot of insight into technical trading and provide some good jumping-off points to developing systems that are TRULY profitable. I have yet to see (or develop) one that I would be willing to risk real money on and I would caution readers from thinking that either of the two systems presented will provide the type of profits described in the book.

To all others (probably the vast majority of those interested in this book!) I would say be very careful before spending your money on this. There is no reliably turn-key system provided in this book, even though there are two that are purported to be such. ... Read more

Product Description
Shrinking pixel sizes along with improvements in image sensors, optics, and electronics have elevated DSCs to levels of performance that match, and have the potential to surpass, that of silver-halide film cameras. Image Sensors and Signal Processing for Digital Still Cameras captures the current state of DSC image acquisition and signal processing technology and takes an all-inclusive look at the field, from the history of DSCs to future possibilities.

The first chapter outlines the evolution of DSCs, their basic structure, and their major application classes. The next few chapters discuss high-quality optics that meet the requirements of better image sensors, the basic functions and performance parameters of image sensors, and detailed discussions of both CCD and CMOS image sensors. The book then discusses how color theory affects the uses of DSCs, presents basic image processing and camera control algorithms and examples of advanced image processing algorithms, explores the architecture and required performance of signal processing engines, and explains how to evaluate image quality for each component described. The book closes with a look at future technologies and the challenges that must be overcome to realize them.

With contributions from many active DSC experts, Image Sensors and Image Processing for Digital Still Cameras offers unparalleled real-world coverage and opens wide the door for future innovation. ... Read more

well done, up to date
Junichi Nakamura did a great job in assembling these chapters by a number of knowledgeable authors on most aspects of state-of-the-art CMOS and CCD imager design. I've only read more carefully the chapters on optics and CMOS pixel design, but I found them both very well written and inclusive of recent advances and challenges.The book also includes appendices on background material, e.g. photometry. From someone who worked on imagers in Silicon Valley, I highly recommend this book for anyone who wants to see inside contemporary imager design.

Great book on electronics of digital still cameras
This book focuses on image acquisition and signal processing in digital still cameras (DSC's). From the perspective of the flow of image information, a DSC consists of imaging optics, an image sensor, and a signal processing block that receives a signal from the image sensor and generates digital data that is eventually compressed andstored on a memory device in the DSC.

Chapters one and two are at a rather high level and introductory. However, in chapter 3 the book gets much more specific. Chapter 3 discusses the functions and performance parameters common to CCD and CMOS image sensors. Chapter 4 describes in detail the CCD image sensors widely used in imaging applications.The chapter ranges from a discussion of basic CCD operating principles to descriptions of CCDimage sensors specifically designed for DSC applications. Chapter 5 discusses CMOS image sensor technology. Chapter 6, the final chapter focusing on sensors, describes methods for evaluating image sensor performances relative to DSC requirements.

Chapter 7 shifts gears and begins the discussing of image processing algorithms. The discussion begins with color theory and its application to DSCs. Chapter 8 presents the algorithms utilized by DSC's in both hardware and software. Basic image processing and camera control algorithms are shown along with some image processing examples. Chapter 9 discusses the performance parameters for DSCs and digital video cameras followed by descriptions of the architectures of signal processing engines. Examples of the analog front-end and the digital back-end designs are introduced. Chapter 10 shows how each component previously described affects image quality. The final chapter discusses future DSC image sensors and explores a new paradigm for image sensors.

The reader should have an electrical engineering background since there are quite a few circuit diagrams shown involving transistors, and it is hard to follow the discussion if you are not already aware of their theory of operation. It is a very good book for its target audience, but students with pure computer science backgrounds who are coming to this looking for just the mathematics or algorithms of image processing may found themselves lost in the discussions involving pn junctions, which are numerous.

One of the best technical book on Cameras and Sensors
I have reviewed quite a few books on cameras and image sensors.Being in the business, I have quite a large library of books related to this field.However, Nakamura nailed it all with this book.A very well written - almost in layman's terms - that addresses all the technical components that make up a camera.If you are looking to understand the principles of a digital camera, this book is for you.

A nice book to own for reference and research
I read many parts of this book and I think that
it was well written for a wide range of users from optics to image quality metrics.

I strongly recommend it to all graduate students/engineers in CMOS imaging.

I wish I got it during my grad studies....but it is never late to learn and enjoy!!! :-)

I give 10 stars to this book...Good luck and hope to see more like this.

Note: I hope to see the optics chapter be re-written and posted with corrections on the Web. I believe this should be done soon and mentioned in amazon.com. Thank you.

Higly recommended for professionals
This is an excellent book. It covers a wide range of topics in a very detailed manner, suitable for university level students and professionals.

So far I have found only one error in the book. There is something terribly wrong in paragraph 2.2.2, page 32. It is stated that "Depth of the field - ... - is proportional to the square of the focal length of the imaging optics."In fact, the depth of field is inversely proportional to the focal length. Then Eq. 2.11 on page 33 is described once as giving a hyperfocal distance (above the equation) and below the equation is described as giving the depth of the field. I think this part seems to be missing some lines.

Overall, I highly recommend this book if you are looking for something at a technically advanced level.

Authors, try again... could almost have been very good !
This book attempts to cover the DSP field from a non too mathematical approach - which is nice. You would however need an electronic engineering back ground to understand what is discussed in general. The book is goodfor a conceptual overview of DSP but sadly lacks depth to a great extent. Idid however find it useful and would recommend it for beginners assupplementary reading material.

There are better introductory DSP books out there.
I found the book to be lacking in background material, and consequently difficult to follow at times.At the same time the book didn't go far enough to give you a real sense of how to implement DSP.

Great book if you have an advanced math degree and know nothing about Java
If you happen to be the .000001% of the population that has an advanced math degree but has somehow never been exposed to Java, and suddenly find yourself in need of a tutorial on digital signal processing, well, this would be the book for you.For everyone else, look elsewhere.The first half of the book is a Java tutorial that was unnecessary when the book was first published (who buys a book on digital signal processing to learn Java basics?), and by this point is exceedingly dated.The second half of the book, when it finally gets down to the processing of digital signals, goes from 0 to 90 faster than the eye can follow.Chapter 5 starts by explaining what a microphone does, and by its third page is offering equations that would leave a math major scratching his head, with hardly a word of explanation.Sentences like "Digital signal processing is a kind of data processing" are quickly followed by "The constants, known as Fourier coefficients, are found by correlating the time dependent function, x(t), with an Nth harmonic sine-cosine pair."I'm not saying the second sentence doesn't convey important information -- but it needs a bit more context.

Oh, and on top of that, the typos and typesetting problems throughout the book make it (if possible) even more difficult to understand what's happening.(On p. 260, for instance, it's important to note that "210" should be written "2^10".It makes a slight difference to the equation.)

The only question I have now is whether to allow the book to continue taking up space on my shelf, or foist it off onto some other unsuspecting reader.

The author's image processing book is better
Everything that this book says on sound processing has long since become obsolete with the progression of Java and the advent of Java sound. The only real reason to ever buy this book - the Java FFT application - is included in the author's book on image processing, which is still worth having because of the included algorithms. The book does read like a Javadoc, plus the first four chapters are a very inadequate tutorial on the Java programming language as it existed in 1997 and have absolutely nothing to do with signal processing in Java. Also, all of the source code is now available online for download without the book. You can find it by typing "DocJava homepage" into Google. The top address should be the one you're looking for, which shows links which include a homepage for this book. That homepage includes updated source code for this book which was last upgraded in 2003. The source code was really the only reason to ever have the book in the first place, as the narrative and explanations are sorely lacking. The following is the table of contents:

1. Java and Its Promise - An overview of the Java programming language as it was in 1997.
2. Java Programming: The Basics - Very basic stuff on the rules of programming in Java.
3. The Graphical User Interface - Discusses Java's AWT and various associated classes that existed for drawing back in 1997.
4. Futil Recipes for Feudal Times - Mainly discusses the classes for performing data and file I/O in Java, but the author introduces a few inventions of his own such as his Java to HTML converter.
5. Digital Audio Processing - In 1997, about all that the Java programming language could do with sounds was play a few basic file formats. This chapter talks about these classes plus the author's ulaw CODEC, Oscillator, and oscilloscope classes.
6. Digital Audio Transform Recipes - The author talks about his classes for the FFT, IFFT, and PSD. He also talks about how to filter audio using these classes.
7. An Introduction To Image Processing - First the author talks about Java native classes for image processing. Then he introduces his PixelPlane class which gives the programmer a high-level interface to pixel-based operations. This stuff is now all built into various Java API's.
8. Digital Images and Image Formats - This is a general discussion of image formats including bitmap versus vector formats, color depth, compression methods, and discussions of several specific graphics formats such as GIF and JPEG.
9. Image Processing in Java - Since JAI did not exist in 1997, the author has many classes that assist with image processing tasks. These include classes for histograming, a 2D FFT, raster/vector conversion, conversion between color models, affine transformations, and a few special effects. If this chapter interests you, you might want to get the author's other book "Java Image Processing" where he goes into this subject in depth.

Concise technical info hard to find elsewhere.
It is hard to find Java specific information on DSP and this book does the job admirably. Plenty of code examples and a rather monolithic Java application (that's a good thing!) are included. Update at authors websitehighly reccomended.

Is Bonehead Java 101 a corporate publishing requirement?
Maybe I should have the first chapters of my novel be a dictionary of all the words I use with more than four syllables. Then I can add content to my novel without having to be creative!

It reads and informs like a javadoc listing
I was so excited to see a Java book on DSP. I was terribly disappointed with this book however. Firstly, it uses Java 1.0.x, not Java 1.1.x. This startled me since the book was published in 1998. The 4 chapter 'intro tojava' programming tutorial is pointless since anyone pursuing a topic asadvanced as DSP should know the language they are going to work in! Therest of the book reads like Javadoc output interspersed with comments fromthe author. I really wanted to love this book but ultimately I've grown tohate it. ... Read more

Still the best reference
I purchase this book back in 1979.Though I have purchased other newer books about processing digitized speech I always find myself going back to this book as a reference.No other engineering book does as good a job of describing characteristics of the speech signal.

Great Sale
The book is what the seller said it would be and in a good shape, delivered on time

Overall decent book
Good introduction to various speech processing techniques. Attempts were made to cover very broad areas such as speech synthesis, coding, and recognition; which obviously cannot be done in a single volume. The serious readers looking to specialize in any of the mentioned areas must find other sources for more thorough info. Also note that many materials in the book are already outdated due to rapid technological advances.

A Masterpiece in Engineering
This is the book to have on your shelf if you are a serious about speech processing. The authors give a through treatment to the fundamental issues involved in speech processing. This outstanding work of two leaders in DSP and Speech processing, will help you to get started with the fascinating subject of speech processing. The issues covered in the book are still relevant today as it was back in 1970's. Though a bit dated this work is a classic.

The best speech processing book out there!
I am currently doing research for a speech processing project, and as I went through a good number of books, I was not able to find a more complete and technical source as Digital Processing of Speech Signals. In myopinion, the book has a perfect combination of theory and practice whenpresenting both time-domain and frequency-domain algorithms for speechanalysis and synthesis. I originally borrowed this book from a library, butnow I am getting my own. It is a must-have classic! ... Read more
