I agree with the above reviewer - this text is more analytical than I would have liked. The organization was not very helpful for understanding the big picture - how are the different methods for time-frequency analysis related? As an engineer, most of this book was not very useful for me, although there are some nice chapters (e.g. the Wigner distribution). In addition, it is somewhat out of date (wavelets are called scale here), has some errors in the proofs, and could be updated with a new edition.
