Fourier Series, Amplitude
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
the limited signal constructed from its fourier series is shown in
and the spectrum is shown in magenta.
When activated the following gif image show how the applet should appear.
