Square Wave response of Resonant RLC circuit.

Cuthbert Nyack
The transfer function of an RLC circuit is shown below.

Where Q = woL/R, wo = 1/(LC)½.
The applet below shows the effect of passing a square wave through an RLC circuit. The input square wave is shown in magenta. The ouput "square" wave is shown in red. Input spectrum is in green and white and orange show the even and odd parts of the spectrum of the output. The resonant frequency wo is geven in terms of 2p/T.

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