(ii) (iii) A filter that averages input samples over a certain interval is called “running average" and they have the following form: y[n] = 1 M + 1 bb=1/3*ones(1,3); ww -pi:(pi/200):pi; H=freqz(bb,1,ww); subplot(2,1,1) plot(ww.abs(H)) subplot(2,1,2) plot(ww,angle (H)) = M Show that the frequency response for the three-point running average operator is given by: H(ejw) -Σx[n-k] k=0 2 cos w+1 3 %<--Phase (Hint: Use time-shifting property) Implement (4) directly in Matlab. Use a vector that includes 400 samples between - and - for w. Plot the magnitude and phase of (4) with abs() and angle(). e-jw The following Matlab statements will compute H(ejw) numerically and plot its magnitude and phase versus w. %<--Magnitude (4) (ii) (iii) A filter that averages input samples over a certain interval is called “running average" and they have the following form: y[n] = 1 M + 1 bb=1/3*ones(1,3); ww -pi:(pi/200):pi; H=freqz(bb,1,ww); subplot(2,1,1) plot(ww.abs(H)) subplot(2,1,2) plot(ww,angle (H)) = M Show that the frequency response for the three-point running average operator is given by: H(ejw) -Σx[n-k] k=0 2 cos w+1 3 %<--Phase (Hint: Use time-shifting property) Implement (4) directly in Matlab.
