MATLAB Central - Steve on Image Processing » Continuous-time Fourier transform basics The existence of multiple transform flavors, as well as the details of their relationships, is at the heart of much of the confusion on this topic. Let's start with the continuous-time Fourier transform. (When the context makes it clear whether I'm talkin

Fast Fourier transform - Wikipedia, the free encyclopedia A fast Fourier transform (FFT) is an algorithm to compute the discrete Fourier transform (DFT) and its inverse. Fourier analysis converts time (or space) to frequency and vice versa; an FFT rapidly computes such transformations by factorizing the DFT matr
