Book Description
This introductory text examines digital filtering-the processes of refining signals-and its relevance to many applications, particularly computer-related functions. Assuming only a knowledge of calculus and some statistics, the text concentrates on linear signal processing, with some consideration of roundoff effects and Kalman filters. Numerous examples and exercises. Index.
Reviews:
This book introduces major concepts of digital filters. The author starts with the basics (why should we care about digital filters) and ends up with quite complicated things such as recursive filters. This is an excellent book on introductory/intermediate level. In a short, concise form it explains everything what an average engineer/scientist/student who is not involved into professional development of digital filters needs to know about them. What I liked most about this book is that the presentation of the material is very self-consistent. R.W.Hamming starts with the simplest things and proceeds to the next section only when everything what the reader will need in the following is explained. I think, its an excellent buy, especially for this price.
Hamming famously said, "The purpose of computing is insight, not numbers." This book follows that philosophy: it's a clear, step-by-step development of simple FIR filters, which will make that part of the digital filtering world accessible to almost anyone. It's at about a third-year undergraduate level, very suitable for self-teaching, and contains lots of lore that will help keep you out of trouble. My only complaint is that it doesn't even dip a toe into recursive filters or optimal FIR filters, so that it is far from a complete treatment. If you're new to digital filtering, especially if you don't have an electrical engineering background, this is your book.
Dr. Hamming explains about aliasing just by using cos and sin relation, without using any transform domain concept which is a typical explanation method in most books. His explanation about frequency resolution also fascinates me.
