Automatic gain control

Imagine you are at a party and there are loud speakers playing music. Sometimes, the music can get too loud and hurt your ears. Other times, the music may be too soft and you can’t hear it properly. Automatic gain control is like having a friend who is constantly checking the volume of the music and making sure it is just right for your ears.

In technical terms, automatic gain control (AGC) is a system that helps adjust the strength of an audio signal to a consistent, predetermined level. This means that if the volume of the sound gets too loud, the AGC will automatically reduce it. On the other hand, if the volume of the sound gets too soft, the AGC will increase it. The idea is to make sure that the sound level never goes beyond a certain limit or becomes too difficult to hear.

AGC is used in many different applications such as radios, televisions, and microphones. For example, when you listen to the radio while driving a car, the music may be too loud when you are driving fast and too soft when you slow down. The AGC helps to adjust the volume so that you can enjoy listening to the radio at a consistent volume no matter how fast or slow you are driving.

In summary, automatic gain control is a system that helps adjust the volume of sound to a consistent, predetermined level. It ensures that the sound is never too loud or too soft and can be used in a variety of applications to ensure that you have the best possible listening experience.
