First -- use an 8 kHz sampled speech signal (or higher), the Discrete Hilbert Transform, filters, etc., and implement the algorithm we outlined in class (and in the handout). Start with a scrambler using a fixed foldover frequency and finish with a Fancy Scrambler that uses a set of random foldover frequencies. Recovery is achieved using the same type of scrambler to undo the frequency inversion. Second -- implement a voice scrambler of your own devising. Any type of scrambling...

Use Bilinear Transform to design a lowpass Butterworth digital filter that passes frequencies up to f=1500Hz with minimum gain -7dB. The filter is to block frequencies from f = 3600Hz with a maximum gain-38dB. The sampling frequency is f = 8000 a) Find the Butterworth Filter Order = (N), 3-dB Cutoff frequency, and the numerator and denominator coefficients of the H(z) b) Which of the frequencies in the followingx()will be passed by your designed filter?x(t) = cos(1600πt)+5cos(8000πt)+3cos(2300πt)+ 2cos(1400πt)
