Negative Positive
Title: Very good book, but not perfect.
Review: The author does a very good job explaining the fundamentals of DSP with some advanced topics. Materials are clearly, concisely, and logically presented with the exception of the section on FFT(Fast Fourier Transform), here the author's presentation suddenly degraded from excellent to (very)poor, and readers have to sort out the details of what the author is trying to say. Besides convolution and discrete fourier transform, FFT is the most important topic for people beginning on DSP, so this kind of spoils the book somehow. But then, this is still a very good book and the author has spent some great effort on it.
