ECE 5765 Modern Communication Fall 2006, UMD Experiment 3sometimes be found. For example, setting x = L/2 in the Fourier sine series gives f(x = L/2) = h = 4h π sin π 2 + 1 3 sin 3π 2 + 1 5 sin 5π 2 + ··· and this leads to a nice (but slowly converging) series representation for π/4: π 4 = (1−1/3+1/5− 1/7+ 1/9···). Alternatively we may represent the square wave as an even function. 3.Represent the square wave f(t) as a Fourier series. an = 1. Find the Fourier series representation for the function f(t) below.
