Fourier Analysis

Three graphs, showing successive partial Fourier series of a square wave, overlayed onto the original square wave. Each successive Fourier series more closely resembles the original square wave.

The first three successive partial Fourier series (shown in red) for a square wave (shown in blue). The second half of the course is devoted to Fourier series and Fourier integrals. (Image by user Jim.belk on Wikipedia and is in the public domain.)
