چکیده

The publication of the Cooley-Tukey fast Fourier transform (FIT) algorithm in 1965 has opened a new area in digital signal processing by reducing the order of complexity of some crucial computational tasks like Fourier transform and convolution from N 2 to N log2 N, where N is the problem size. The development of the major algorithms (Cooley-Tukey and split-radix FFT, prime factor algorithm and Winograd fast Fourier transform) is reviewed. Then, an attempt is made to indicate the state of the art on the subject, showing the standing of research, open problems and implementations. Zusammenfassung. Die Publikation von Cooley-Tukey's schnellem Fourier Transformations Algorithmus in 1965 brachte eine neue Area in der digitalen Signalverarbeitung weil die Ordnung der Komplexit/it von gewissen zentralen Berechnungen, wie die Fourier Transformation und die digitale Faltung, von N 2 zu N log2 N reduziert wurden (wo N die Problemgr6sse darstellt). Die Entwicklung der wichtigsten Algorithmen (Cooley-Tukey und Split-Radix FIT, Prime Factor Algorithmus und Winograd's schneller Fourier Transformation) ist nachvollzogen. Dann wird versucht, den Stand des Feldes zu beschreiben, um zu zeigen wo die Forschung steht, was flir Probleme noch offenstehen, wie zum Beispiel in Implementierungen. Rrsum4.

Pathologies cardiac discrimination using the Fast Fourir Transform (FFT) The short time Fourier transforms (STFT) and the Wigner distribution (WD)

This paper is concerned with a synthesis study of the fast Fourier transform (FFT), the short time Fourier transform (STFT and the Wigner distribution (WD) in analysing the phonocardiogram signal (PCG) or heart cardiac sounds.     The FFT (Fast Fourier Transform) can provide a basic understanding of the frequency contents of the heart sounds. The STFT is obtained by calculating the Fourier tran...

FFT Algorithms

The DFT usually arises as an approximation to the continuous Fourier transform when functions are sampled at discrete intervals in space or time. The naive evaluation of the discrete Fourier transform is a matrix-vector multiplication W~g, and would take O(N) operations for N data-points. The general principle of the Fast Fourier Transform algorithms is to use a divide-and-conquer strategy to f...

Chapter 1 Fast Fourier Transforms for Nonequispaced Data: a Tutorial

In this section, we consider approximative methods for the fast computation of multivariate discrete Fourier transforms for nonequi-spaced data (NDFT) in the time domain and in the frequency domain. In particular, we are interested in the approximation error as function of the arithmetic complexity of the algorithm. We discuss the robustness of NDFT{algorithms with respect to roundoo errors and...
