plot convolution of two ct signals in matlab in matlab

To plot the convolution of two continuous-time signals in MATLAB, you can follow these steps:

1. Define the two continuous-time signals. Let's say we have signal x1(t) and x2(t).

main.m
t = -5:0.01:5; % Time vector
x1 = sin(t); % Define the first signal x1(t)
x2 = exp(-t.^2); % Define the second signal x2(t)

2. Calculate the convolution using the conv function in MATLAB.

main.m
y = conv(x1, x2); % Convolution result y(t)

3. Create the corresponding time vector for the convolution result.

main.m
t_conv = linspace(min(t)+min(t), max(t)+max(t), length(y));

4. Plot the results using the plot function.

main.m
figure;
subplot(3,1,1);
plot(t, x1); % Plot the first signal x1(t)
title('Signal x1(t)');
xlabel('Time');
ylabel('Amplitude');

subplot(3,1,2);
plot(t, x2); % Plot the second signal x2(t)
title('Signal x2(t)');
xlabel('Time');
ylabel('Amplitude');

subplot(3,1,3);
plot(t_conv, y); % Plot the convolution result y(t)
title('Convolution of x1(t) and x2(t)');
xlabel('Time');
ylabel('Amplitude');

By running this code, you will obtain a figure with three subplots. The first subplot shows the first signal x1(t), the second subplot shows the second signal x2(t), and the third subplot shows the convolution result y(t).

Note: Make sure to adjust the time vector t to cover the appropriate range for your signals.

Remember to replace x1 and x2 with your actual signal expressions. Please let me know if you need any further assistance.
