I have a problem: I need to design an amplifier system in which I need to switch to a lower gain when clipping occurs. So I am thinking of something like this:
---------->-------------> op amp A (large gain) --------> output A
|
|
---------------> op amp B (smaller gain) ---------> output B
So that I can read output A when no clipping occurs and output B when clipping occurs. I am trying to avoid using variable gain op amps since I have no microcontroller at the moment in my design. My question is: is this design undesirable? Will this splitting of signals create noise?
