Fast Fourier Transform. An algorithm for computing the Fourier transform of a set of discrete data values. Given a finite set of data points, for example a periodic sampling taken from a real-world signal, the FFT expresses the data in terms of its component frequencies. It also solves the essentially identical inverse problem of reconstructing a signal from the frequency data.

An acronym for Fast Fourier Transform, a technique for very fast computation of Fourier series. A discrete Fourier transform using N points can be computed in N log N steps by the fast method, whereas the straightforward method would take N**2 steps. fine grain:
