It introduces how to realize the TVG(Time-Variant Gain)curve control and MGC(Manual Gain Control)of the high-frequency sonar receiver in one type of intelligent underwater vehicles based FPGA design.

Study on automatic gain control method of pulse oxygen saturation measured;

Instantaneous automatic gain control scheme in PRS;

Design of automatic gain control in WLAN with RF2607;

As an important part of digital receivers,Automatic Gain Control(AGC) circuits are usually used to reduce the loss of C/N0.

In poor PLC communication environment,the stability of the signal can only be realized by improving the level of Automatic Gain Control(AGC).

It make it realizable to select 256 testing poits, and it also actualizes automatic gain control(AGC)for different amplitude signals and optimizes the accuracy of signal collection.
