how to produce 12 pulse in matlab

One way to produce a 12 pulse in Matlab is to use the built-in function called "square". This function generates a square wave with a specified duty cycle and frequency.

To generate a 12 pulse, we need to create a square wave with a duty cycle of 50% and a frequency of 6 times the fundamental frequency. Here's the code to generate the 12 pulse:

main.m
f0 = 50; % fundamental frequency
fs = 1000; % sampling frequency
t = 0:1/fs:1/f0; % time vector
t(end) = []; % remove last element to avoid division by zero

% create square wave
duty_cycle = 50; % 50% duty cycle
f12 = 6*f0; % 6th harmonic frequency
square_wave = square(2*pi*f12*t, duty_cycle);

% plot result
plot(t, square_wave);
xlabel('Time (s)');
ylabel('Amplitude');

This code creates a time vector t that ranges from 0 to the period of the fundamental frequency, with a step size of 1/sampling frequency. It then creates a square wave with a frequency of 6 times the fundamental frequency and a duty cycle of 50%. Finally, it plots the square wave.

Note that the sampling frequency fs must be at least twice the frequency of the square wave to avoid aliasing.
