WebJan 10, 2014 · Q1: I'm trying to understand the difference between DTFT and DFT in general terms. DTFT is used to find frequency components of a discrete-time continuous signal or sequence and it is periodic over period of 2π, and most importantly it takes into account all the sampled valued from -∞ to +∞. Please correct me if I have it wrong. WebQuestion: 1) The Fourier transform for a discrete time (DT) signal is periodic, with period 2π rad/sample, and with highest possible frequency π rad/sample. Thus the DTFT is fully specified over the range-π ω π. Determine the Fourier transform X(ej") for-π ω π for the following signals.
