Automatic Gain Control (AGC) in Radio Systems: Principles and
AGC is a closed-loop control system that manages the gain for one or more amplifiers. Its main job is to keep the
The automatic gain control (AGC) function ensures that the signal gain of existing channels is not affected when wavelengths are added in a WDM system, or when one or more wavelengths are dropped or the optical power fluctuates. In this way, services carried on a WDM network will not be affected. Now AGC circuits can be found in any device or system where wide amplitude variations in the output signal could lead to lose of information or to an unacceptable performance of the system. Download this Guide in PDF format In order to set the AGC control on the module, and specifically for the transmitter module. Automatic gain control (AGC), sometimes Automatic volume control (AVC) is a closed-loo...
