[TriEmbed] Ground Confusion

[Scott Hall]

I read a good article that explains this phenomenon and why in Circuit Cellar
magazine in the last few months.  If I can dig up the text from their electronic
copy, I'll post it here.

Gist of it is, you minimize ground loops and signal paths where real-world parts
and materials have impedance and generate noise and oscillations.  More
specifically you minimize power ground noise from the control signals.
