Abstract

A signal combining system employed for transmitting a plurality of pulse signals, in which if binary information of the same polarity is continuously transmitted for a period of time, in comparison with the last bit of the preceding period of time, in a main input communication circuit such as a facsimile circuit, signal combining is effected to insert therein other prestored binary information from another communication circuit. The above signal combining is performed for information blocks, each of which includes at least one sign bit for distinguishing pulse signals of the main communication circuit and another communication circuit from one another.
