Suppose an audio amplifier produces 8.0 V rms output with 80 mV rms input.
Suppose the amplifier input impedance is the same as the output load impedance.
What is the gain of this amplifier in this situation?
a. 20 dB
b. 40 dB
c. 100 dB
d. 200 dB
e. We must know the actual input and output impedance values, in ohms, in order to determine the gain in this case.
