ABSTRACT:
An arrangement for determining the phase position between two signals includes a circuit containing a gate with two inputs for the signals and an output for a first output signal which is dependent on the phase position between the input signals. A flip-flop has an input for one of the input signals and a second input for the first output signal. The second input of the flip-flop contains a time-delay circuit for the first output signal. Two similar circuits can be used.
