Automatic Gain Controller Circuit
A.G.C : Automatic gain control is a technique found in many electronic devices. The advantage or peak output signal level is used to adjust teh gain to a suitable level, enabling the circuit to work satisfactorily with a greater rang of input signal levels. Examples, without AGC the sound emitted from an AM radio receiver would vary to an extreme extent from a weak to a strong signal, the AGC effectively reduces the volume if the signal s strong and raises it when i is weaker.
