Wikipedia Overview
In mathematics, the discrete Fourier transform (DFT) is a discrete version of the Fourier transform that converts one finite sequence of function values into another of the same length. The DFT converts back and forth between two different representations of a trigonometric polynomial: a representation in terms of the function values at equispaced sample points, and a representation in terms of the polynomial coefficients. The DFT is a useful tool when considering any sufficiently smooth periodic function, because by taking sufficiently many sample points, a trigonometric polynomial will approximate it to any desired degree of accuracy, and trigonometric polynomials represented in terms of their coefficients are computationally convenient objects to work with.
