What does reverse AGC voltage do in a receiver?

Reverse AGC (Automatic Gain Control) voltage in a receiver is primarily designed to manage the level of gain applied to the incoming signal based on its amplitude. When a strong signal is received, the reverse AGC voltage is increased, effectively driving the amplifiers toward cutoff. This action helps to prevent overload and distortion in the receiver by reducing the gain of the signal.

By pushing the amplifiers toward cutoff, the receiver can maintain a more consistent output level, which is especially important in preventing strong signals from overwhelming weaker ones. This process ensures that the receiver can handle varying signal strengths without compromising the quality of the audio or data being transmitted.
