Problem 4 The System function of a LTI system is given by H(2) (1-z-1)(1 + z-1) 1 - 1.13142-1 + 0.64z-2 Use MATLAB to sketch the magnitude spectrum |H(W) and phase spectrum (w). Problem 5 A third order lowpass filter is described by the following difference equation y(n) = 1.76y(n − 1) - 1.1829y(n − 2) + 0.2781y(n − 3) + 0.0181x(n) + 0.0543x(n − 1) + 0.0543x(n - 2) + 0.0181x(n-3) Use MATLAB to sketch the system magnitude response |H(w) and and phase response (w). Verify that the the filter is a lowpass filter. Is the phase linear?
