ABSTRACT:
Optical receiving system, incoming unipolar pulses being converted into bipolar pulses having a constant top amplitude (elements 2, 3 and 4) which, on the one hand, are used for generating replicas of the original pulses, but having a constant top amplitude (element 5) and, on the other hand, for eliminating mutual phase differences by means of phase comparison with local clock pulses (elements 7..14). The latter is preferably effected by the bipolar pulses being multiplied (element 7) by the clock pulses, and by using the resulting DC signal to control a controllable delay element (8).
