Book Description

November 11, 2010 0137027419 978-0137027415 3’s Top-Selling DSP Book for Seven Straight Years—Now Fully Updated!


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

5.0 out of 5 stars Takes the mystique out of DSP April 8, 2013
Format:Hardcover|Verified Purchase
If you are planning to get into DSP from a practical point of view, then there are only two books to get - and this is one of them. DSP is a complex subject, and if you are not in an educational environment where you have easy access to teachers who can advise you, then you could easily be turned off by diving into a book such as Schafer and Oppenheim's recognized text book on the subject. I am a retired ex-academic with an interest in signal processing, and decided to get back into the field, which had developed considerably since I was involved in basic continuous signal processing, which than revolved around Fourier analysis and integrals. I researched the market thoroughly and ended up purchasing Steven Smith's excellent book "The Scientist and Engineer's Guide to Digital Signal Processing", which gives a conceptual view of DSP without getting too involved in the mathematics of the subject. Having worked through this book and established a solid basis of what DSP is all about, I decided that I needed a little more mathematical support to the concepts, and settled on the current book. What a good choice. These two books are a perfect complement to each other, and the writing style of the authors is very similar. Anybody getting into DSP is strongly advised to purchase them both. But back to the current book - this book focuses on the reader and makes you feel that you are interacting with a teacher rather than puzzling over equations. It leads you gently through the concepts, but doesn't bypass thorough considerations of the development, for instance, of the Fast Fourier Transform, which can be quite intimidating. This is a chapter that you can scan through without disrupting the rest of the material. Read more ›

5.0 out of 5 stars Still a DSP classic September 29, 2011
Rick's book is a clear and engaging textbook on digital signal processing. The style of the book is much more easy-going than many introductory DSP books. Even with the easy-going attitude, the author does not dumb-down the technical accuracy required to do high-level DSP effectively. The emphasis in this book is on getting the reader to understand the technical concepts; if the reader understands the concepts, they should get the maths right.

When I wrote the review of the first edition (the paragraph above), it was true. Each subsequent edition has only improved the text. [Disclaimer: I have no commerical interest in the book, but I did help Rick revise small parts of it.]

3.0 out of 5 stars Unnecessarily verbose February 11, 2011
Format:Hardcover|Verified Purchase
DSP authors often bombard readers with equations and lack any genuine explanation and "feeling" for what they represent.

Lyons tries to avoid this by limiting equations and providing more explanation.

The problem and annoying thing about his writing, however, is that he provides almost no structure or conciseness. Often he rambles on aimlessly on topics that really do not require much explanation. Like beating a dead dog over and over again, the reader is frustrated glancing over the pages to see when he will actually get to something useful.

And this is where the trouble begins. Many times in introducing new topics, he does not provide important details at the beginning but rather drops them off like bombs in mid sentences on ramblings. For example, when introducing the topic of DFT's, he provides the equation for DFT but rather than right away explain the fact that X(m) represents the frequency component of the signal at mfs/N he mentions nothing until two pages later in an unrelated ramble! Such way of explanations are fine if you are attentive and read every word carefully, but they can also frustrate readers.

Generally, not a bad book and better than most DSP books out there, but still lacking in presentation and conciseness.

5.0 out of 5 stars Exceptional presentation of DSP fundamentals. January 10, 2012
Format:Hardcover|Verified Purchase
My review is based on the second edition. I've been using this book for the last four (4) years. I wish i'd purchased it ten (10) years ago.

Core DSP concepts are made clear and intuitive. Lyons' pedagogical style is comparable to Steven Smith's introductory book (Digital Signal Processing: A Practical Guide for Engineers and Scientists, also freely distributed online at author's Web site). Math is used only when needed and generally kept to a minimum---a refreshing approach for such a technical topic.

This book, along maybe with Schaums Outline of Digital Signal Processing, 2nd Edition (Schaum's Outline Series), should form a good basis for conceptually understanding the fundamentals and beyond, so that upper undergraduate and graduate courses on DSP become more enjoyable. Lyons' clarity is uncommon. The breadth of the book is also commendable.

The book is not a substitute for the classic texts on DSP (Proakis, Oppenheim & Schafer, Manolakis) or Fourier theory (Bracewell, Papoulis); judging by his style, neither does the author make a pretense it is. Rather, this is a much needed attempt to gap the math--intuition gap so many of us have struggled with over their beginning DSP years. And a very successful one at that. Truly an exceptional and welcome addition to the DSP literature.
