Assume circuit below:
How can we implement a circuit with equivalent performance in which we can change both of resistance of potentiometers with only one volume? in the other word, we have just one potentiometer but we need to change gain of both Op-Amps identical (for example for two AC input signals, both Op-Amp amplify 10x that is control with one volume).
