a. The precision full-wave rectifier in Fig. (a) has R1 = R2 = RF = R = 10 kΩ , R3 = 40 kΩ , and R4 =40 kΩ . The input voltage is vS = 2 sin (377 Πt). Plot the transfer characteristic and draw the waveform of the output voltage vO.
b. Use PSpice/SPICE to plot the transfer characteristic and the output voltage.
