Two feedback configurations are shown in figures a and b at, Ask an Expert

Engineering

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, A_f = V_o/V_i, for the two feedback circuits.

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