[sdiy] Analog vs. Digital grounds and Doepfer power bus.

[Bret Truchan]

Hello!

I love this forum!  I'm a little confused.  I've been told that it's a good 
idea to keep ICs grounds and analog grounds separate.  When I look at my 
Doepfer power bus, it has three grounds.  Do the Doepfer modules utilize the 
different grounds to keep their analog and digital ground separate?  If so, 
how do you know which one to use for what?

Or, are the three grounds on the power bus tied together?

Thanks!
- Bret
