Question

MY code is experiencing a problem as I want to show both the magnitude ratio on low pass, high pass, and bandbass based on passive filters:

Code:

% Define frequency range for the plot
f = logspace(1, 5, 500); % Frequency range from 10 Hz to 100 kHz
w = 2*pi*f; % Angular frequency
 
% Parameters for the filters (you can modify these)
R = 1e3; % Resistance in ohms (1 kOhm)
C = 1e-6; % Capacitance in farads (1 uF)
L = 10e-3; % Inductance in henries (10 mH)
 
% Transfer function for Low-pass filter: H_low = 1 / (1 + jωRC)
H_low = 1 ./ (1 + 1i*w*R*C);
 
% Transfer function for High-pass filter: H_high = jωRC / (1 + jωRC)
H_high = 1i*w*R*C ./ (1 + 1i*w*R*C);
 
% Transfer function for Band-pass filter: H_band = jωRC / (1 + jωL/R + jωRC)
H_band = 1i*w*R*C ./ (1 + 1i*w*L/R + 1i*w*R*C);
 
% Plot magnitude responses
figure;
subplot(3,1,1);
semilogx(f, 20*log10(abs(H_low))); % Low-pass filter
title('Magnitude Response of Low-pass Filter');
xlabel('Frequency (Hz)');
ylabel('Magnitude (dB)');
grid on;
 
subplot(3,1,2);
semilogx(f, 20*log10(abs(H_high))); % High-pass filter
title('Magnitude Response of High-pass Filter');
xlabel('Frequency (Hz)');
ylabel('Magnitude (dB)');
grid on;
 
subplot(3,1,3);
semilogx(f, 20*log10(abs(H_band))); % Band-pass filter
title('Magnitude Response of Band-pass Filter');
xlabel('Frequency (Hz)');
ylabel('Magnitude (dB)');
grid on;
