Hi,

For this circuit:

For measuring the "120VAC-x" signals at 200kHz bandwidth what would a
good way to do this?

just a simple resistor divider could work too.

This would be a good way to go since the output is not isolated from
what I can see.

Also:

If you make a bandpass filter that takes the voltage directly from the
switches, you can improve the loop responce. It gives you something
very like the "D" part for your PID controller.


cheers,
