Abstract

A gain control system for a receiver that combines some of the features ofoth limiting and AGC. The AGC loop of the present invention has a relatively long time constant which reduces the gain so that the desired signal is only 10 to 15 db into limiting. This degree of limiting provides instantaneous control of small changes in signal level, but prevents the receiver from instantaneously opening to full gain in the case of loss of signal. This prevents erroneous data from being received during a time interval in which it is expected that the original signal will return.
