ABSTRACT:
The invention relates to a phase detector, especially for a Phase Locked Loop of a desynchronizer of a digital transmission system for the transmission of signals of the synchronous digital hierarchy with a difference former (subtractor) connected to a comparator, to which can be conducted at the input side, via a first accumulator, a first input signal, and via a second accumulator a second input signal with the comparator being connected at the output side via a coder to a control input of the second accumulator.
