4.12 This problem compares the Blackman-Harris and Hamming windows in the frequency domain. Write a program to construct the coefficients of a lowpass rectangular window filter with a cutoff frequency of 200 Hz. Make the filter length $L = 33$ coefficients. Assume $f_s = 1000$ Hz. Generate and apply the appropriate length Hamming (Equation 4.24) and Blackman-Harris (Equation 4.25) windows to the filter coefficients, $b[k]$. Construct the two windows from the basic equations as in Example 4.5. Find and plot the spectra of the filter without a window and with the two windows. Plot the spectra superimposed to aid comparison and pad to 256 samples. As always, do not plot redundant points. Note that the Hamming window produces a somewhat steeper attenuation, but has just the slightest ripple before the cutoff.
