This book presents in a unified way the various fast algorithms that are used for the implementation of digital filters and the evaluation of discrete Fourier transforms. The book consists of eight chapters. The first two chapters are devoted to background information and to introductory material on number theory and polynomial algebra. 1 Introduction.- Introductory Remarks.- Notations.- The Structure of the Book.- 2 Elements of Number Theory and Polynomial Algebra.- Elementary Number Theory.- Divisibility of Integers.- Congruences . Lausanne HENRI J. NUSSBAUMER April Preface to the First Edition This book presents in a unified way the various fast algorithms that are used for the implementation of digital filters and the evaluation of discrete Fourier transforms. The rest of the book is focused directly on fast digital filtering and discrete Fourier transform algorithms. We have attempted to present these techniques in a unified way by using polynomial algebra as extensively as possible. This objective has led us to reformulate many of the algorithms which are discussed in the book.

It demonstrates the importance of computational number theory in the design of digital signal processing algorithms and clearly describes the nature and structure of the algorithms themselves. The book has two primary focuses: first, it establishes the properties of discrete-time sequence indices and their corresponding fast algorithms; and second, it investigates the properties of the discrete-time sequences and the corresponding fast algorithms . Introduction --Elements of number theory and polynomial algebra --Fast convolution algorithms --The fast Fourier transform --Linear filtering computation of discrete Fourier transforms --Polynomial transforms --Computation of discrete Fourier transforms by polynomial transforms --Number theoretic transforms.

The Fast Fourier Transform (FFT) Algorithm. The FFT is a fast algorithm for computing the DFT. If we take the 2-point DFT and 4-point DFT and generalize them to 8-point, point, , 2r-point, we get the FFT algorithm. To computetheDFT of an N-point sequence usingequation (1) would takeO.N2/mul- . This book focuses on the discrete Fourier transform (DFT), discrete convolution, and, particularly, the fast algorithms to calculate them. These topics have been at the center of digital signal processing since its beginning, and new results in hardware, theory and applications continue to keep them important and exciting.
