Query: Digital Filters, Andreas Antoniou

This is NOT meant as a review, but as a suggestion, to help you to sell this and related books.Antoniou's book is an applied form of digital signal processing, and is of general interest to your other clientele who look for info in that area, yet your recommended list of subject areas makes no mention of DSP, which has hordes of good related material.Suggest you revamp your connections to the Antoniou book, to make sure it gets mentioned when people are looking for other DSP books.
