ABSTRACT:
An AGC circuit for controlling an input level of a multi-level discriminator to an optimum one and a transversal equalizer capable of fully exhibiting an equalizing function thereof, each being installed in a digital demodulation system applicable to a multi-level communication system. The AGC circuit eliminates false pull-in to promote stable pull-in operations and is applicable not only to baseband signals having two or more levels but also to a 16 QAM system in microwave digital communication. Even when a demodulator is in an asynchronous state and input signals have significant intersymbol interference, the demodulation system is capable of being restored to normal to allow the equalizer to fully exhibit its capability.
