D)increase, increase

Question

Quizplus · Accepted Answer

Removing a bypass capacitor from a fully bypassed, common-emitter amplifier circuit will decrease the voltage gain because the capacitor normally bypasses the emitter resistor for AC signals, increasing the gain. Without it, the AC gain decreases. It will increase the AC input resistance because the emitter resistor is no longer bypassed, adding its impedance to the input.
