Question

Quizplus · Accepted Answer

The AC gain of a four-resistor bias circuit is set by the ratio of RC to RE. This is because the AC gain is equal to the ratio of the output voltage to the input voltage, and the output voltage is equal to the voltage drop across RC, while the input voltage is equal to the voltage drop across RE.
