Overview / Usage

A Fourier series is a periodic function composed of harmonically related sinusoids, combined by a weighted summation. With appropriate weights, one cycle (or period) of the summation can be made to approximate an arbitrary function in that interval.

For the generation of square wave, the odd harmonics of the sine wave are superimposed and hence a square wave is generated.
As the number of terms to be summed is increased, the shape becomes more and more square.

Methodology / Approach

The function of a square wave is transformed into a Fourier Series and implemented using p5.js, a javascript library.
