A fast Fourier transform (FFT) is an algorithm that computes the discrete Fourier transform (DFT) of a sequence, or its inverse (IDFT). A Fourier transform converts a signal from its original …

The discovery of the Fast Fourier transformation (FFT) is attributed to Cooley and Tukey, who published an algorithm in 1965. But in fact the FFT has been discovered repeatedly before, …

The algorithm in this lecture, known since the time of Gauss but popularized mainly by Cooley and Tukey in the 1960s, is an example of the divide-and-conquer paradigm.

This paper provides a brief overview of a family of algorithms known as the fast Fourier transforms (FFT), focusing primarily on two common methods. Before considering its mathematical …
