First post! I'll try to make it a good one.
I've gotten into the habit of designing PCBs for my electronic projects instead of trying to shove them onto a project board. However, that's brought up a lot of other things I have to learn.
One thing I've seen discussed many times, with much support on both sides is the separation of ground planes by analog/digital or by high speed/low speed/analog circuits.
Notice, I said separation and not splitting. The hot topic I've seen is that some people think physically splitting the ground planes with "bridges" that the traces run over is the best way to do things. While other people think that a single ground plane, with the circuits divided by an imaginary line, is a better idea. I've seen tons of support for both methods, with papers and research to back them up.
The point is to keep high speed digital current (and current return) away from the analog circuitry.
I've read the following PDF which seems to support the single ground plane idea. What I want to know is... what do you do? I'm sure anyone that answers this thread has a ton more knowledge than me, so i just wanted to hear some ideas.
EDIT: Yes, I did get the PDF from a thread on this exact subject on this site.
