5. 20 points. Suppose a = 0.9ej7/4 and suppose G(z) = (1 - Bz-1)(1 - 8*z-1) = 1 – 2Re(B)2-1 +18122-2. = a Find a value for B E C such that ß a, ß # a*, and such that G(z) has the same magnitude response (to within a constant scale factor) as H(z) with a = 0.9ej#/4 but has a different phase response. Use Matlab's freqz command to plot the magnitude and phase responses of H(z) with a = 0.9e37/4 and G(z) with your choice of ß.
