Understanding Digital Signal Processing, 3/e is simply the best practitioner's resource for mastering DSP technology. Richard Lyons has thoroughly updated and expanded his best-selling second edition, building on the exceptionally readable coverage that has made it a favorite of both professionals and students worldwide. Lyons achieves the perfect balance between practice and math, making DSP accessible to beginners without ever oversimplifying it, and offering systematic practical guidance for day-to-day problem-solving. Down-to-earth, intuitive, and example-rich, this book helps readers thoroughly grasp the basics and quickly move on to more sophisticated DSP techniques. Coverage discrete sequences/systems, DFT, FFT, finite/infinite impulse response filters, quadrature (I/Q) processing, discrete Hilbert transforms, sample rate conversion, signal averaging, and much more. This edition adds extensive new coverage of FIR and IIR filter analysis techniques. The previous multirate processing, and binary number format, material has been significantly updated and expanded. It also provides new coverage of digital differentiators, integrators, and matched filters. Lyons has also doubled the number of DSP tips and tricks as in the previous edition including techniques even seasoned DSP professionals may have overlooked. He has also added end-of-chapter homework problems throughout to support college instruction and professional self-study.
One of the best textbooks I've read. The author's tone is fantastic. Here's an example: "Unfortunately, many authors make a statement like 'and we know that,' and drop [equations] on the unsuspecting reader who's expected to accept these expressions on faith. Assuming you don't have a Ph.D. in mathematics, you may wonder what arithmetic sleight of hand allows us to arrive at [these equations]."
The book is very well balanced. When it explores key equations or identities in detail, it provides intuitive, comprehensive explanations. When it omits proofs, it does so in order to maintain a brisk, interesting pace (also providing references to literature with more information). I imagine one would be hard-pressed to find a better introduction to the subject.
Lots of books are titled, "Understanding..." but this one actually works. I have read what I needed from chapters 1-5, 8 and the layout and explanations are exceptional to the point where a nincompoop like me can understand what is going on.
Anybody interested in DFTs, complex numbers, the imaginary plane, and quadrature need no longer wonder what the hell is going on. This book explained imaginary numbers and phasors better than any of the math books I currently own.
A great text book and interesting for engineers and math nerds.
best DSP textbook. It reads very conversational and he doesn’t assume too much mathematically. Still rigorous and deep where it should be, but it’s not just a book full of equations you have to make sense of. I read it as supplementary material for a course, was extremely helpful.
A friendly and easy introduction to the subject. As a cosmologist, I know well what Fourier transforms are but damned if I ever had to actually compute a DFT in an applied setting, worrying about windowing, aliasing, and Nyquist frequencies. Lyons takes you by the hand and whispers, calmly but assuredly, "it will be all right, child." Overall, a gentle and useful guide to the concepts underlying DSP.
This is the best book on DSP for practicing engineers. If you need to implement a solution to a DSP problem or use the FFT, this book provides all the information you need to know. It has a very practical focus, which is a relief compared to most DSP resources.
