How to Plot FFT for the iztrans function?

3 次查看(过去 30 天)
I have received the inverse z transfer function for a filter. I need to plot the FFT for that. I tried a lot but it doesn`t work. Could you please support with me to plot the FFT? I am new to this area.

Try this code. may be this code will help you.
% Define the transfer function coefficients
b = [1, -1]; % Numerator coefficients
a = [1, 0.5]; % Denominator coefficients
% Generate the frequency response using freqz
N = 1024; % Number of points for the frequency response
[H, f] = freqz(b, a, N);
% Plot the magnitude spectrum
figure;
plot(f, abs(H));
xlabel('Frequency');
ylabel('Magnitude');
title('Magnitude Spectrum');
% Plot the phase spectrum
figure;
plot(f, angle(H));
xlabel('Frequency');
ylabel('Phase');
title('Phase Spectrum');
