Determine the change in closed loop gain

Assignment Help Electrical Engineering
Reference no: EM131225219

Two feedback configurations are shown in Figures (a) and (b). At low input voltages, the two gains are A1 = A2 = 90 and at higher input voltages, the gains change to A1 = A2 = 60.

Determine the change in closed-loop gain, Af = Vo/Vi, for the two feedback circuits.

(See Figure) Which feedback configuration will result in less distortion in the output signal?
