About this document

DTFT Computation via DFT in Matlab by manjuvenamma is a document available to read on EtoBox.

This Matlab code computes the discrete-time Fourier transform (DTFT) of a signal using the discrete Fourier transform (DFT). It takes the DFT of a unit sample signal with different lengths and plots the results against the theoretical DTFT to show they converge as the length increases. Specifically, it takes the DFT with lengths of 8, 16, and 50 samples and overlays the results on a plot of the DTFT to demonstrate the convergence.
