Fourier Series, Amplitude limited Sine.

Cuthbert Nyack

In real circuits, the amplitude of signals are often limited by the characteristic of the circuits eg supply voltage. This can give rise to voltage limited signals.

The applet below shows how the spectrum of a signal is affected by limiting. The "unlimited" amplitude of the sinusoid is given by the parameter "a" and the limited amplitude is 1. The limited signal is shown in green the limited signal constructed from its fourier series is shown in red and the spectrum is shown in magenta.

When activated the following gif image show how the applet should appear.
