Hello there,
I'm trying to build a "doomsday-machine" and I'm kinda stuck at this problem.
I have a 200mV peak-to-peak signal riding on a +6V offset, now I would like to remove the +6V offset so that the signal oscillates between 0-200mv, however the problem is that i'm constrained by:
1. low low frequency 0.001Hz or less, so I can't use a simple cap
2. +12V single supply environment, so I can't use a diff op-amp
I would appeciate any suggestions, I'm really stuck.
Thanks in advance
