SIGNALOVERFORINGSANLEGGNING

摘要

A facsimile signal transmission system including a transmitter in which a store provides a high frequency signal during signal repetition periods which signal is, for example, frequency-modulated. This signal is applied to a counting circuit in which a continuous count is effected with binary numbers associated with a plurality of outputs. A counting signal is applied each signal repetition period to a second counting circuit so that one binary number occurs at a plurality of outputs during each period. The first and second counting circuits are connected to a coincidence stage for supplying a signal in case of equal binary numbers to a transmission channel having a limited bandwidth to a receiver. The receiver includes a store for cyclically meshing storage of the received signal so that after a number of signal repetition periods equal to the maximum counting number of the counting circuits the high frequency signal is present in the receiver.
