Understanding Digital Signal Processing (2nd Edition)

Real-world DSP solutions for working professionals!

Understanding Digital Signal Processing, Second Edition is quite simply the best way for engineers, and other technical professionals, to master and apply DSP techniques. Lyons has updated and expanded his best-selling first edition-building on the exceptionally readable coverage that made it the favorite of professionals worldwide.

This book achieves the perfect balance between theory and practice, making DSP accessible to beginners without ever oversimplifying it. Comprehensive in scope and gentle in approach, keeping the math at a tolerable level, this book helps readers thoroughly grasp the basics and quickly move on to more sophisticated techniques.

This edition adds extensive new coverage of quadrature signals for digital communications; recent improvements in digital filtering; and much more. It also contains more than twice as many "DSP Tips and Tricks" including clever techniques even seasoned professionals may have overlooked.

Down-to-earth, intuitive, and example-rich, with detailed numerical exercises
Stresses practical, day-to-day DSP implementations and problem-solving
All-new quadrature processing coverage includes easy-to-understand 3D drawings
Extended coverage of IIR filters; plus frequency sampling, interpolated FIR filters
New coverage of multirate systems; including both polyphase and cascaded integrator-comb FIR filters
Coverage includes: periodic sampling, DFT, FFT, digital filters, discrete Hilbert transforms, sample rate conversion, quantization, signal averaging, and more

This is a must-read as an introduction on DSP. Books like Franklins et al.'s "Digital Control of Dynamic Systems" or Oppenheim's "Discrete Time Signal Processing" are not meant to be introductory textbooks...but once you'll be done with this one then you can go to the more advanced ones.

For another introductory book, the one from Proakis and Manolakis also deserves a mention, but Lyons's is my first choice for introduction. Lyons's style and presentation are better... I would recommend using Lyons for a first iuntroduction and then to Proakis and Manolakis for further mastering the subject, but staying at an introductory level...

I'm a grad student in EE, and have had half-a-dozen DSP classes over the years. Many questions have remained unanswered over this time and I'm happy to say that this book filled in the missing pieces. Judging from the topics Lyons chooses to elucidate, it is obvious that he has traveled this confusing road himself, emerging victorious on the other side of the tunnel. He graciously shares his hard-won information with the reader, shedding light on various ubiquitious DSP confusion causing topics (i.e. convolution, digital filter design methods, DFT/FFT, etc.) If you're a EE that needs to really acquire an intuitive feel for DSP, this book is the answer. He doesn't dumb down the subject, either. Although one can certainly delve deeper (many references are provided), Lyons does a good job of explaining and describing the math. He has a wonderful colloquial style that makes it seem like you're discussing this stuff with a buddy. I can't recommend this book high enough. It's worth several times the purchase price.


One of the best technical books I've read   April 7, 2003

I'll agree with the other glowing reviews here. This is one of the finest technical books I've ever read. It does a really great job of explaining concepts like the FFT so you can really understand them. A great introduction!
