[sdiy] Some info on the Laplace transform and the s-plane

[cheater00 .]

Hi guys,
I've come across a couple exceedingly simple explanations of the
practical usage of the s-plane. It's good for stuff like audio
circuits.

The simplest, most basic tutorial on obtaining a Laplace-domain
transfer function: http://www.youtube.com/watch?v=ZgUVpjvOn5I

The s-plane and Nyquist plots:
