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. Signal 5 can be written as a cosine times a rectangular pulse, so the ... IMPULSE RESPONSE-1 0 1-1-0.5 0 0.5 1 5 Real Part Imaginary Part ZEROS OF H(z)
