This book has a great outline with all of the classic treatments of the subject; Complex numbers, Digital Filters, Fourier analysis, etc. A solid foundation is set forth in early chapters in a mixed of theory and heuristic explanation to present to a wide range of experienced reader. The key issue I have between rating this book a full 5 stars is that of notational inconsistency and the rather poor synchronization of the text with the figures. There are several places where the author is referencing a figure and the reader is left wonder if the individual generating the figures discussed the figure with the author prior to publishing the book. For example, the discussion of phasors includes a graph of a sine wave with a peak magnitude of 1. The accompanying equation mysteriously has the value 10sin(...). This seems minor at first glance yet there other examples of an apparent disconnect between text and associated figures. Some of the equations referenced appear unchecked. For example, i(t) = Re{10exp(j*w*t + phi)} = Re{10exp(j*2*pi*t)} = Re{10*exp(j*phi)} (Reviewer note: f =1 in this equation and omission of f was acceptable)?

In summary, the book is good but could have been better proof read prior to publication; in this reviewer's opinion.

Digital Signal processing has changed tremendously in recent years. The advent of ever higher performance processors have all but elminimated using analog circuits to process analog signals. Both the faster CPUs, and the advent of specialized single instruction multiple data (SIMD) instructions have made digital signal processing much easier. Combining the new instructions with specialized software (included on the enclosed CD, including MatLab and SciLab) has completely changed the nature of signal processing.

This book starts with a solid mathematical foundation before going on to more practical applications. It is not a For Dummies book, the mathematics is certainly college level.
