摘要：
A carrier phase correction circuit for a data communications system is provided which includes an automatic transversal equalizer and which utilizes the voltage control signals that are connected to the attenuators for the two taps adjacent to the central tap of the transversal equalizer, which signals are used in equalizing the baseband input to the equalizer. The two signals are compared and a first output produced when one of the signals is greater and a second output produced when the second is greater, the two outputs being used in controlling advancing and retarding the recovered carrier phase.
