## Description

Understanding Digital Signal Processing [Lyons, Richard] on desertcart.com. *FREE* shipping on qualifying offers. Understanding Digital Signal Processing

Review: academic art - I very rarely write reviews **this book is a must purchase** lucid explanations abound - and I especially appreciate the presentation as I came from undergrad compsci into graduate EE. Lyons' ability to make you arrive at the inevitable conclusion that is the concept is as delightful as it is Socratic. personal highlights: chapter 5 presentation of convolution and FIR filters. I legit instantly grasped the concept of convolution that had been "taught" to me many times before. I immediately understood why we "reverse" one signal in time for convolution. I recognized why passband ripple was inevitable without modifying one's window chapter 8 explanation of imaginary/complex numbers, Euler's identity and relations, in-phase/quadrature, negative frequency, and how a real signal can be composed of real and imaginary sinusoids. ***this chapter, alone, is worth picking up the book.*** I do not say that lightly! this book does not teach inasmuch as it facilitates one's realization that certain phenomena MUST arise due to the underlying mathematics. but it does not take anything beyond even vague familiarity with Calculus 2. given the subject matter, that is absolitely incredible. for context, I took Calc 2 15 years ago and was able to keep pace. beyond that, the book incurs an obvious intuition that is lacking in so many texts I genuinely wish I had been exposed to this book wayyy earlier
Review: A great reference for actual applications - I had been searching for a good DSP reference book, when I found Understanding Digital Signal Processing 3rd ed. in desertcart. 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.

### ⭐⭐⭐⭐⭐ Takes the mystique out of DSP
*by K***N on April 8, 2013*

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. The book includes many exercises and - best of all - Rick Lyons has a DSP blog of tips and tricks where you can get invaluable information and interact directly with him. All in all, by purchasing this book you not only get a source-book of the practical application of DSP, but a wealth of support, and I have no hesitation in awarding it a 5-star rating.
