Definitions of DISCRETE FOURIER TRANSFORM
Sort: Oldest first
(DFT) A Fourier transform, specialized to thecase where the abscissas are integers.The DFT is central to many kinds of signal processing,including the analysis and compression of video and soundinformation.A common implementation of the DFT is the Fast FourierTransform (FFT).See also discrete cosine transform.
