EL 713: Digital Signal Processing Extra Problem Solutions

The DTFT of a rectangular pulse is a digital sinc function, so the DFT of a rectangular pulse is samples of the sinc function. So signal 8 corresponds to DFT 5. That leaves signal 5 and DFT 8.

Impulse Response and Convolution

Impulse Response A CT system is completely characterized by its impulse response, much as a DT system is completely characterized by its unit-sample response. We have worked with the impulse (Dirac delta) function δ(t) previously. It’s de ned in a limit as follows. Let p ∆(t) represent a pulse of width ∆ and height 1 ∆ so that its area ...
