Design a minimum-length linear-phase bandpass filter of Problem P7.9 using the Parks-McClellan algorithm.
1. Plot the impulse response and the magnitude response in dB of the designed filter in one figure plot.
2. Plot the amplitude response of the designed filter and count the total number of extrema in passband and stopbands. Verify this number with the theoretical estimate of the total number of extrema.
3. Compare the order of this filter with that of the filter in Problem P7.9.
Problem P7.9
Design a linear-phase bandpass filter using the Hann window design technique. The specifications are
