plural of discrete Fourier transform

(mathematics) The process of converting a discrete time-based function into its frequency-based representation.

plural of fast Fourier transform

(mathematics) A mathematical operation that transforms a function for a discrete or continuous spectrum into a function for the amplitude with the given spectrum; an inverse transform of the Fourier transform.

A member of a certain family of algorithms for efficiently computing the discrete Fourier transform of data. / An instance of performing one of these algorithms.

(category theory) A natural transformation whose naturality squares are pullbacks.
