Create a Square Wave function without using the Matlab function square.

Hello! I would love to learn how to make a Square wave funtion to generate a unit amplitude with a 440 Hz square wave. A duty cycle of 0.2, 0.5 and 0.8, that last for 2 seconds. Using a sampling frequency of 44.1kHz.

Inputs are:

• Duty-cycle
• Total time for which the square wave is defined
• Sampling Frequency
• Fundamental frequency

OUTPUT:

• Square Waveform

All I have done

function [waveform] =SqWave(DutyC,Tt,Fs,Ff)

DutyC = 0.2;

Fs = 44100;

Further work : I will keep researching and find a solution but in the mean time I would like to hear feedback.
