WebDigital Signal Processing - DFT Introduction. Like continuous time signal Fourier transform, discrete time Fourier Transform can be used to represent a discrete sequence into its equivalent frequency domain representation and LTI discrete time system and develop various computational algorithms. X in continuous F.T, is a continuous function of x. WebThe Mathematica notebook “dft.nb” was used to generate the examples in this set of notes. In subsequent notes, we will continue our discussion of the DFT, including windowing methods that can alleviate the problem of spec-tral leakage. We will also talk about the FFT as a computationally efficient algorithm for computing the DFT, and
