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)
