Fast Fourier Transform
A method by which to decompose data into a sum of sinusoids of varying cycle length, with each cycle being a fraction of a common fundamental cycle length.
Fast Fourier Transform
Decomposes a periodic series of data into its component frequencies.

Fast Fourier Transform: An efficient algorithm to compute the discrete Fourier transform (DFT) and it's inverse.
The complete Fourier analysis concept is called spectral analysis. Fast Fourier Transform ("FFT") is an abbreviated calculation that can be computed in a fraction of the time.
