D) automated stepping voltage

Question

Quizplus · Accepted Answer

Automatic gain control (AGC) is a technique used in electronics to automatically adjust the gain of an amplifier in response to variations in the signal level. It is commonly used in radio receivers, where it helps to maintain a constant output level regardless of variations in signal strength.
