This document describes a lab report on the discrete time Fourier transform (DTFT) conducted between March and July 2012 at CECOS College of Engineering and IT. The lab was designed by Dawar Awan and explores properties of the DTFT including examples, time and frequency shifting, convolution, and time reversal through computer programs. Students are tasked with running the programs using different parameters and sequences to analyze and comment on the results.
