Hello all,
I am having trouble thinking of how to deal with an unknown voltage. I am creating a circuit for an experiement that will read an input voltage and that input is unknown. The problem is that this voltage affects how the output looks. If the amplitude is too high or low, I need to adjust the reference voltage at a different part of the circuit. However, no one will be around to adjust the reference voltage to account for the unknown voltage when the experiement is going on. So I'm not sure how to get around this problem. If anyone has any suggestions, I would appreciate it. Also if there is anything unclear in how I explained the problem, let me know.
