# Category:FFT algorithms

Computing portal |

Here is a list of articles in the category **FFT algorithms** of the Computing portal that unifies foundations of mathematics and computations using computers. This category is for fast Fourier transform (FFT) algorithms, i.e. algorithms to compute the discrete Fourier transform (DFT) in O(*N* log *N*) time (or better, for approximate algorithms), where [math]N[/math] is the number of discrete points.
