It is an honor to be the first Amazon customer to review this book. The two DSP books which have received so far the highest Amazon customer reviews are those by Steven Smith and Richard Lyons. Proakis is a close third, though one reviewer says that its reader may wish to have Smith and Lyons in hand to help with understanding. This book by Li Tan belongs in the top three or four, if not the very top. My qualification for commenting on it comes from having just audited a graduate level DSP course, in which I happened to discover this book, along with the books by Stevens and Lyons, at the university library and used for outside study. The Smith and Lyons books were very helpful, but this one seemed to follow the course itself much more closely (actually covering material beyond the course), and so it was the most helpful of all. It is loaded with step by step, helpful examples, and also matlab code examples, some of which are particularly revealing and helpful. (Thank you for reading my review.)

I think the reason DSP is preceived as difficult to understand, is because traditional book/class tend to spend most of the time solving equations such as DFT, FFT, Z-transform of different signal (pulse, unit step, sinusoidal, square, triangular etc), differential equation to get zero and pole, stability, then bilinear transformation etc. As a result, students might spend all the time doing mathematics, than trying to understand what DSP is and how to apply it to real world.

This book reduce the mathematics and proof to minimum when required, rather than throwing you all the equations and explanation at one time. For example, I dont always why other authors always try to explain the details of non-causal system since they usually say real time system is always causal and hence ignore the non-causal DSP design.

I particularly like the exercise and MATLAB code. They are incredibly simple, but are very useful to aid understanding and cover almost all aspect of a DSP system, from equalizing ADC quantising noise, through to multirate DSP (which is rarely touched by most of the fundamental DSP books). The MATLAB code allows the reader to design filter and visualise the signal and its frequency spectrum very quickly. I think it is more important for beginner to first understand the concept of DSP using MATLAB, than trying to solve the mathematics, try to write C-code for FFT and plotting graph.

As I mentioned, the mathematics is not detailed in this book. This is a double edge sword. Reader should have good knowledge on FFT, Z-transform. I recommend reading "Understanding Digital Signal Processing" by Lyons beforehand, which provide very good explanation on fundamental DSP theory and mathematics.

This is the most useful DSP book I have ever read!!!!

Its a book with information that I needed for school. I'm not sure how to rate this other than it has a lot of information, it's easy to read, and it has a ton of MATLAB examples. MATLAB will help you out immensely because there are some VERY LONG calculations that MATLAB does in one command.

I am 3rd year Electrical Engineering student. I have recently taken a math course aimed specifically at the advanced math in this subject. I still have a hard time following the huge gaps between equation manipulation in this text.

I am going to try the Steven Smith book to help salvage the course I am taking with this book as the textbook.
