It is not often that you find a book that presents information as clearly and precisely as this one.
From the opening chapter the authors have worked hard to make this book interesting, with illustrations, block diagrams, design tips and practical advice on almost every page.
Particularly useful are the 4 tool boxes - chapters in the book with down to earth algorithms for the designer.
Theory is there when you need it, but the authors are not trying to show off here, rather to communicate DSP is a simple and easy to digest manner.
An excellent book all round.
