[sdiy] S-plane visualization software

[Oren B. Leavitt]

Hello,

As a programmer by trade, I have been trying to think of ways to put that lazy
PC to work in a synth-DIY-useful way, too.

I like the idea of an interactive filter designer - I just might write an app if
I find some spare time.

Where can I get some backgrounders on the math and theory involved?
I will need examples, equations, and graphs, etc... to get an idea.

I am not up to snuff on s-plane filter math...I think I mis-Laplaced my
head...;-)

Cheers! Oren
