Hello everyone, I have this question. Any help in appreciated. ^_^

Building a square wave. It is defined as f(t) = {1 if 0 < t < T, -1 if –T < t < 0}.

a. Create a script that plots a single square wave. Label the graph.

b. Change the above script to include a train of square waves consisting of 4 squares pieces.

Try repmat() or repelem(), or use the square() function.

Hi. So are you saying for part b, I am going to use one of these functions?

For part a, I'd use linspace to create T. Then I'd use ones() to create an array of 1's. Then I'd use indexing to set some of them to -1. Then I'd use plot(), title(), xlabel(), and ylabel() to make the plot.

For part b, I'd use repmat() to replicate the single pulse from part a.
