In mathematics the finite Fourier transfor … In mathematics the finite Fourier transform may refer to either
* another name for discrete-time Fourier transform (DTFT) of a finite-length series. E.g., (pp. 52–53) describes the finite Fourier transform as a "continuous periodic function" and the discrete Fourier transform (DFT) as "a set of samples of the finite Fourier transform". In actual implementation, that is not two separate steps; the DFT replaces the DTFT. So (pp. 77–78) describes the implementation as discrete finite Fourier transform. or
* another name for the Fourier series coefficients. or
* another name for one snapshot of a short-time Fourier transform.napshot of a short-time Fourier transform.
