Hi,
I want to plot the amplitude and the phase response of the following system:
I have the following code, but need help with the plots.
% Parameters
fs = 2000;
dt = 1/fs;
r = 0.99;
w0 = 700;
% Transfer function
numerator = [1,-2*cos(700),1];
denominator = [1,-2*cos(700)*r,r^2];
sys = tf(numerator,denominator,dt,'Variable','z^-1')

You can use the bode command to get the magnitude and phase response. Try:
bode(sys);
