EEL3135: Discrete-Time Signals and Systems Fourier Series Examples - 1 - Fourier Series Examples 1. Introduction In these notes, we derive in detail the Fourier series representation of several continuous-time periodic wave-forms. Recall that we can write almost any periodic, continuous-time signal as an inﬁnite sum of harmoni-cally Example 1 Find the Fourier series for f(x) = L − x on − L ≤ x ≤ L. Fourier Series Example Example: Determine the fourier series of the function f (x) = 1 – x2 in the interval [-1, 1]. Fourier Series Example Example: Determine the fourier series of the function f (x) = 1 – x2 in the interval [-1, 1].

As an example, let us find the exponential series for the following rectangular wave, given by L = 1, and their Fourier series representations involve terms like a 1 cosx , b 1 sinx a 2 cos2x , b 2 sin2x a 3 cos3x , b 3 sin3x We also include a constant term a 0/2 in the Fourier series. This allows us to represent functions that are, for example, entirely above the x−axis.
