Hi Roberto,
I understand that you want to find the power of a given periodic signal with a normalized load resistance of 1 ohm and plot it.
To implement this, kindly refer to the following code snippet -
% Calculate the power of the signal
T = t(end) - t(1); % Calculate the period of the signal
instantaneous_power = abs(y).^2;
power = (1/T) * trapz((t, instantaneous_power) / load_resistance));
disp(['The power of the signal is: ' num2str(power) ' Watts']);
To plot the power of the signal, kindly refer to the following code snippet -
Figure
plot(t, instantaneous_power, 'LineWidth', 2)
xlabel('t');
ylabel('Power');
title('Power of the Signal');
grid on;
For more information regarding “trapz” and “plot” functions, kindly refer to the following documentation:
I hope this answer resolves your query.
Regards,
Nithin Kumar.
