Resistor networks are sometimes used as volume-control circuits. In this application, they are referred to as resistance attenuators or pads. A typical fixed-attenuator pad is shown in the figure. 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 Rabboth have a specified value. (Figure 1) Resistors [Ω] 10 100 1.0 k 10 k 100 k 1.0 M 120...
