For a fun project I've been trying to create some sort of circuit that behaves as follows:
- Two outputs, Vout1 and Vout2.
- One Input Vin
- 1 Controlling potentiometer Rpot from 0-MAX.
- Any combination (and amount) of BJTs, MOSFETs, capacitors, inductors, and resistors.
What I'm trying to accomplish is this: An AC signal enters the circuit. When Rpot is at some middle value say Rpot = .5MAX, both outputs are essentially in parallel and connected to the source Vin. Vout1 and Vout1 must receive the same signal (or very very close, 1-5mV off), and also must have at least 90% of the magnitude that Vin has (so if Vin has an amplitude of 1V, Vout1 and Vout2 must have an amplitude of ~.8V or better).
As Rpot is increased to its MAX value, I want to decrease the amount of the signal that Vout1 or Vout2 receives.
For Example: As Rpot increases to MAX, Vout1 = 1V amplitude while Vout2 = .5V And if Rpot approaches its 0 value then Vout2 = 1V amplitude while Vout1 = .5V
While the amplitudes I'm using are arbituary I think it gets what I'm trying to accomplish across. As I either increase or decrease the resistance of Rpot, I only want one output to attenuate at a time.
I've tried numerous voltage divider circuits and tried to use some BJTs to create some logical feedback but I'm running into wall. The closest I've gotten is using a voltage regulator that turns on when one channel is attenuating but I can't quite get it to work. Any help would be appreciated.
Thanks in advance!
