Program must be written in Matlab. *NOTE* You can not use the built in function Square() to complete this task! Thank you.

3. Write a function, SqWave which generates a square wave of specified: duty- cycle, total time for which the wave is generated, and sampling frequency. The function should have the following inputs and outputs: Inputs: Duty-cycle Total time for which the square wave is defined Sampling Frequency Outputs: Square Wave Do NOT use the Matlab function square to accomplish this task. Use the SqWave function to generate a unit amplitude, 440 Hz square-wave, ? 0.1, 0.2, 0.5, that lasts for 2 s. Use a sampling frequency of 44.1 kHz. Play back the tone over your speakers using the sound command. How does the perceived tone change as you vary a
