Understanding Digital Signal Processing

Book Description

Understanding Digital Signal Processing, Third Edition, is quite simply the best resource for engineers and other technical professionals who want to master and apply today’s latest DSP techniques. Richard G. Lyons has updated and expanded his best-selling second edition to reflect the newest technologies, building on the exceptionally readable coverage that made it the favorite of DSP professionals worldwide. He has also added hands-on problems to every chapter, giving students even more of the practical experience they need to succeed.

Comprehensive in scope and clear in approach, this book achieves the perfect balance between theory and practice, keeps math at a tolerable level, and makes DSP exceptionally accessible to beginners without ever oversimplifying it. Readers can thoroughly grasp the basics and quickly move on to more sophisticated techniques.

This edition adds extensive new coverage of FIR and IIR filter analysis techniques, digital differentiators, integrators, and matched filters. Lyons has significantly updated and expanded his discussions of multirate processing techniques, which are crucial to modern wireless and satellite communications. He also presents nearly twice as many DSP Tricks as in the second edition—including techniques even seasoned DSP professionals may have overlooked.

Coverage includes

• New homework problems that deepen your understanding and help you apply what you’ve learned
• Practical, day-to-day DSP implementations and problem-solving throughout
• Useful new guidance on generalized digital networks, including discrete differentiators, integrators, and matched filters
• Clear descriptions of statistical measures of signals, variance reduction by averaging, and real-world signal-to-noise ratio (SNR) computation
• A significantly expanded chapter on sample rate conversion (multirate systems) and associated filtering techniques
• New guidance on implementing fast convolution, IIR filter scaling, and more
• Enhanced coverage of analyzing digital filter behavior and performance for diverse communications and biomedical applications
• Discrete sequences/systems, periodic sampling, DFT, FFT, finite/infinite impulse response filters, quadrature (I/Q) processing, discrete Hilbert transforms, binary number formats, and much more

...go out and buy this book NOW. Mister Lyons has an incredible gift of making out of the most difficult chapters of DSP (like FFT and Filters) a child's play. Something for musicians too who want to understand what they're doing, not just get the latest AU's or VST's or whatever and fool around with "the knobs". A true must-have in my opinion. It really takes you by the hand.

I had been searching for a good DSP reference book, when I found Understanding Digital Signal Processing 3rd ed. in Amazon. The reviews regarding the 2nd ed. we're positive, so I decided to get a copy.

At the same time I was working on a software defined radio for the HF amateur bands. I had little knowledge of I and Q signals, analytic signals, Hilbert transforms - a lot of things that make single sideband modulation/demodulation possible in an SDR.

This book, in addition to extensive coverage of FIR/IIR filtering and related topics, also covers complex/quadrature signals, upconversion/downconversion, Hilbert transform, sample rate conversion, polyphase filtering, etc. in a way that's understandable and applicable. The math is there as one would expect, but then the author also explains things in a physical/real sense. I was able to learn these topics and actually apply them - the fact that I was able to make my SDR work is a testimony to the book.

To summarize - if I need to brush up on a DSP topic, or learn something new, but then APPLY it, this book is an wonderful reference. If you're considering this book, be sure and review the Table of Contents - there's a lot in this book. The Processing Tricks section has been very helpful as well. I can highly recommend this book.

In every field there are books that just stand apart. They are so well written that they change your opinion about the subject. In fact, with most mathematical ideas if you understand them well, they no longer seem tedious, or hard. Richard Lyons book "Understanding Digital Signal Processing" is just such a book. I remember coming across it on Amazon when Amazon was young. This was before Amazon had a "look inside" feature and one was generally leery of ordering things on line. There was a introduction to the book written by the author which I read. The writing style was impressive and so I ordered the book. I still remember looking through and thinking this looks fun! It had more pictures than it had formulas! How often do you get excited looking at a textbook!

I read the first chapter that night and felt exhilarated. I had my first aha moment in DSP. Although I was out of graduate school for several years at that time, I felt that I had never really understood the subject. Yes, I could do the transforms for homework etc., but understood, not really. In this book, Lyons starts with discrete signals, goes through sampling and aliasing in the first chapter. Each chapter build gently on the previous. All just a model of clarity and beauty. I particularly loved the filter chapter, with such easy to understand exposition of what the equation meant, the forward part and the reverse part. We all love pictures and the book's strength is its ability to communicate not just in words but also in figures. From DFT to filter design to DSP algorithms, all come alive as explained by Lyons.

I think I did read the whole book in about a week. I had been writing papers and felt that this is the way engineering should be taught. This is the way engineering books should be written. With the student in mind. No hiding behind formulas. I ordered the new edition of his book and something so good has gotten even better!

I now write a DSP blog called complextoreal and can say without hesitation that this books was my role model in how to explain engineering ideas.

This is just a plain excellent book, deserving of all the superlatives I can muster. Fantastic, etc. etc. If you are a student in this field or an engineer, I recommend that you add this book to your library immediately. - Charan Langton
