The present invention is a digital dynamic compression or automatic gain control (AGC) ( 10) adapted for use in high quality audio and hearing aids applications. An efficient digital AGC design employs two compact ROM-based tables (ROM_CSD, ROM_SPL) in addition to two comparators (COMP_A, COMP_B) and several registers (REG_A, REG_B, ADDR_A, ADDR_B).

The objective of our final project is to develop an automatic gain control system, which includes a Raspberry pi model 3, an audio amplifier, an analog to digital converter (ADC), a digital to analog converter (DAC), and a speaker. Our primary goal is to build a system that can protect speakers by reducing the gain on the audio amplifier when distortion is detected, and increasing gain once …

A new digital method for implementing Automatic Gain Control (AGC) in a hearing aid is described. The AGC characteristics are programmable, which allows the system to be customized for a particular user. Since no external timing components are required the implementation is area-efficient, completely monolithic, and insensitive to temperature ...
Automatic Gain Control - an overview | ScienceDirect Topics

Automatic gain control adjusts the received signal strength in the receive chain, either via analog or digital gain, to a certain desired power suitable for best performance. The gain lineup is manipulated “up or down” while maintaining the best possible signal-to-noise ratio (SNR).

The gain will be at the maximum at that time and can be found out using the following equation: G = – ( R2 / R1 ) dB This particular circuit provides a maximum gain of around 50 dB and holds the amplitude of the output signal constant at 2.5 V p-p from input signal amplitude of 50mV p-p.
