Fourier Analysis is a simple application that illustrates the Fourier analysis of a periodic function.
The expressions L(t) and R(t) define the function on the intervals [min,center] (left) and [center,max] (right). The center may coinside with min or max.
The order of the Fourier polynomial can be chosen betwenn 0 and 200. For "high" order you may experience numerical inaccuracies.
The chart shows 3 periods of the prescribed function. Fourier Analysis has a context menu offering various features, like zooming or exporting. The context menu is accessed via the right mouse button.
