{{page>wiki:headers:hheader}} ===== Homework for Oscillations ===== Find the Fourier series that represents a square wave with period $T$, amplitude $A$. To make the problem simpler, choose the time origin so that the function is odd, and the duty cycle is 50% (duty cycle means "the time in the high state as fraction of the period"). {{page>wiki:footers:courses:osfooter}}
