new here plus a question...

[Bram de Jong]

Hello.

I'm new here, so lemme tell you something about myself :)
I'm a 22-year CS student who's interested in audio and DSP.

I've been messing around with audio programming for a while now, and it
looks like it might be interesting to follow some of the threads over
here. (I got sent here by Andy Mucho, who some of u might know).

U can take a look at my site here: http://www.smartelectronix.com


Now for the question:
There's a long thread going on in the music-dsp list about modeling amps
and cabinets in the digital domain, and while talking to Andy on IRC, he
mentioned this:

http://duncanamps.com/tsc/

Now, I know *something* about digital filter design, but sadly enough I
know next to nothing about analysing analog electronics schemes, nor about
converting them to digital forms. :(

So here's my question: would it be possible to convert these schematics to
the digital domain using bilinear transforms? If so, how should I try
this? Perhaps some of you could help me figure out the transfer functions
on these schematics, as that would help me a lot too.

Andy and me have been pondering about specialised methods that could model
these frequency curves in the digital domain using weird non-linear stuff
like genetic algorithms, but then I'd need the transfer functions again :)

For short: help! ;))

cheers,


Bram.
