Resistor networks are sometimes used as volumecontrol circuits. In this application, they are referred to as resistance attenuators or pads. A typical fixedattenuator pad is shown in Fig. P3.66. In designing an attenuation pad, the circuit designer will select the values of R1 and R2 so that the ratio of vo>vi and the resistance seen by the input voltage source Rab both have a specified value.
c) Choose values from Appendix H that are closest to R1 and R2 from part (b). Calculate the percent error in the resulting values for Rab and v0>v1 if these new resistor values are used.
