Abstract

Feedback Automatic Gain Control (FBAGC) is used to suppress large, slow unwanted variations of a received signal's envelope while passing more rapid required variations. Two ways in which the bandwidth of FBAGC may be kept fixed at the designed value, independent of the input signal are examined. These are exponential-integrator FBAGC systems and dual-path linear FBAGC systems. It is shown that although both systems perform approximately the same operation on the received signal's envelope, the latter has such undesirable practical properties that it should not be considered for use in any form of signal processing system
