Title: Automatic gain control circuit and method

Abstract: An automatic gain control circuit including a wide band digitally controlled amplifier particularly adapted for use with recurring signals. Each of the recurring signals is divided into a large number of discrete time intervals and the gain of the amplifier may be adjusted for each time interval independently of the signal in any other of the time intervals. Transients due to gain modification may be superimposed.
