Question: Repeat Problem for the Hamming window and compare the resulting FIR filter with the FIR filter obtained from the rectangular window in that problem.
Problem: Determine the impulse response of an ideal discrete-time lowpass filter with a cut-off frequency of ?c = 1 radian/s. Using a rectangular window, truncate the length N of the ideal filter to 51. Plot the impulse response and amplitude frequency characteristics of the FIR filter.
