I would like to know if somebody has schematics and explanations about an Automatic gain control, as I am a beginner.

Thanks a lot in advance.

This is for an audio amplifier. An audio signal has to go in an Automatic Gain control whose supply voltage is from 0 to 5 V. After that I will generate a PWM signal by a ST7, an this signal will be rebuilt by a class D amplifier.

But I have a problem with the Automatic gain control.

Thank you for your explanations.
