Understanding Digital Signal Processing (2ed) by Richard Lyons

While Intelligent Sensor Design offers an introduction to the concepts of digital signal processing, this book covers the subject in depth and is simply the best text on DSP that we’ve seen. Not only does Understanding Digital Signal Processing provide a thorough exploration of the important DSP topics, it does so with a writing style that is easy to understand and free of much of the cryptic language found in so many textbooks.

Lyons’ background as a practicing engineer comes through in his writing, with an emphasis on getting results without becoming unnecessarily bogged down in the associated mathematics. His explanation of the concept of “negative frequency” is outstanding and alone is worth the price of the book.
