Excuse the crazy title...but imagine an AGC circuit......basically a peak detector, turning the incoming AC signal into a DC representation...that DC is used that control a voltage control amplifier...all well and good.
But what if we want the AGC level to be user setable (therefore maybe the user wants to increase the output of the circuit...but how can this be arranged?
I'm thinking here that the AGC will always try & pull the output back to the median ...how can I effect what that median is? (and if the result of an AGC circuit is a DC representation of the extracted AC, then how can I increase the DC level without it then trying to self contain itself & negate the introduced elevated DC?)
Maybe I just need more medication? "Nurse...over here ...QUICK"
