Question:
An attenuation pad is a two-port resistance circuit that provides a nonadjustable reduction in signal level while also providing resistance matching at the input and output ports. Attenuators are used in numerous applications such as in audio recording studios to reduce the signal coming from a microphone into an audio mixer.
A picture of a typical commercial in-line attenuator is shown in Figure 3–70(a).
Figure 3–70
(b) shows the circuit of a particular attenuation pad. The manufacturer’s data sheet for this pad specifies the following characteristics at the input and output ports:
