Question: Pulse Distortion Filter the signal pulse with the IIR filter and compare to processing with the FIR filter. Note that when you processed the narrowband signals xl and x2 with the IIR filter or FIR filter, they were scaled and delayed with little distortion of the pulse shape; but when you process the signal pulse through the !IR filter, its pulse shape is severe ly distorted and dispersed in time. Explain why this happens.
