Introduction: The circuit shown in Figure 1 produces an output voltage, v_o, that represents the quantity indicated by a dial connected to the potentiometer. The dial is connected to an 100 kOhm potentiometer indicates an angle -180 deg < theta < 180 deg. Also, take R_i = 50 kOhm and R_f = 250 kOhm.
