ABSTRACT:
A phase detector has a reference signal input for a reference signal and a detector input for a signal to be evaluated. A memory unit is connected to the detector input and stores a state of the signal to be evaluated at a storage instant. An evaluation unit is connected downstream of the storage unit and is designed in such a way that it can be used to compare the stored state of the signal with the state of the reference signal at an evaluation instant and to generate an evaluation result signal therefrom. The phase detector has a control unit for prescribing the storage instant and the evaluation instant, the control unit prescribing the storage instant first and then the evaluation instant. A detector output is connected to the evaluation unit and the evaluation result signal can be tapped off at the detector output.
