Textbook Question

Chapter 12, Problem 12.15P

Two feedback configurations are shown in Figures P 12.15 ( a ) and ( b ) . At low input voltages, the two gains are A 1 = A 2 = 90 and at higher input voltages, the gains change to A 1 = A 2 = 60. Determine the change in closed-loop gain , A f = V o / V i , for the two feedback circuits. (See Figure 12.4.) Which feedback configuration will result in less distortion in the output signal?

Prelab Information 1. Laboratory Preliminary Discussion First-order Low-pass RC Filter Analysis The first-order low-pass RC filter shown in figure 1 below represents all voltages and currents in the time domain. It is of course possible to solve for all circuit voltages using time domain differential equation techniques, but it is more efficient to convert the circuit to its s-domain equivalent as shown in figure 2 and apply Laplace transform techniques. vs(t) i₁(t) + R₁ ww V₁(t) 12(t) Lic(t) Vout(t) = V2(t) R₂ Vc(t) C Vc(t) VR2(t) = V2(t) + Vs(s) Figure 1: A first-order low-pass RC filter represented in the time domain.
