This book is a comprehensive presentation of recent results and developments on several widely used transforms and their fast algorithms. In many cases, new opt

This book presents an introduction to the principles of the fast Fourier transform. This book covers FFTs, frequency domain filtering, and applications to video

This book has grown from notes used by the authors to instruct fast transform classes. One class was sponsored by the Training Department of Rockwell Internatio

Long employed in electrical engineering, the discrete Fourier transform (DFT) is now applied in a range of fields through the use of digital computers and fast
