Fig. 1: Automatic Gain Control Circuit on Breadboard The Automatic Gain Control (AGC) amplifiers are another category of amplifiers which can vary its gain according to the input signal level. They provide enough amplification for the weak signals and prevent strong signals from getting over amplified.

The automatic gain control circuit AGC provides a signal with less harmonics and additional amplification, between certain limits. As a result, it eliminates those intensity differences, annoying, and of speech music, which sometimes appear on radio and television. Field effect transistors T1 is used as a variable resistance.

Automatic Gain Control or AGC is a circuit design which maintain the same level of amplification for sound or radio frequency. If the signal is too low the AGC circuit will increase (amplify) the level and if is to high will lower it to maintain a constant level as possible.
