One can easily advance or delay a square wave. For example, the MATLAB commands

produce a square wave with period T = 4 and duty cycle d=25%, but the wave is “delayed” one second, as shown in Figure.

Figure A square wave that is delayed one second.

Some might find the term “delay” misleading, as the square wave appears to be moved forward one second in time. However, the square pulse does start one second later than usual, hence the term “delay.” Use MATLAB to create a plot of a square wave with

a) amplitude three, period T = 6 seconds, duty cycle d = 25%, that is delayed 2 seconds on the time interval [0, 24].

b) amplitude four, period T = 12 months, duty cycle d = 25%, that is delayed 9 months on the time interval [0,48].
