I've seen feedback. Amazing forms of feedback! Trust me, if sone right, it
works, and it works well!

Also, digital is nothing more than analog circuits with signals that quickly
change between 2 common voltages. Anyone who beleives that digital is not
related to analog has not truly learned. computers need to take account for
those analog effects. Things like rise and fall time, noise, and either way,
it exists. in addition, many digital chips have interesting results when
analog is pumped into them.

I think the reason most people don't believe in feedback is they don't have
the patience to try to make it work. It usualy requires a lot of tuning to
perfect!
Why not use a microcontroler if you want to use digital control.
