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(11-1) + 0.0543x(n-2) +0.0181x(1-3) Use MATLAB to sketch the system magnitude response |H(w) and and phase response 0(w). Verify that the the filter is a lowpass filter. Is the phase linear?
