WebFeb 8, 2024 · If the periodic function doesn’t have an average value of zero (like if it doesn’t oscillate about t-axis), then you need to shift it. That’s that a0/2 term where a0 is just the average value over one period. Let’s do this. Let’s build a model of the square wave using sines and cosines. Sure, we can’t add an infinite number of waves ...
