Before we learn about application of DFT, first let we check it out the DFT stands for Discrete Fourier transform, it is a finite duration frequency sequence which is obtained by sampling one period of Fourier transform. So in sampling is done at 'N' equally spaced points, over the period extending from o to 2π.
