DFT

    (DFT) A Fourier transform, specialized to the
   case where the abscissas are integers.

   The DFT is central to many kinds of signal processing,
   including the analysis and compression of video and sound
   information.

   A common implementation of the DFT is the Fast Fourier
   Transform (FFT).

   See also discrete cosine transform.
