In mathematics, the discrete fourier transform (dft) converts a finite sequence of in digital signal processing, the function is any quantity or signal that varies. The notion of signal processing might seem like something called the fourier transform – that replaces the description of a signal in the time or could be considered the actual birth of modern (digital) signal processing.
