Abstract

A modulator-demodulator device for converting, at the transmitting station, the binary signals into frequency modulated waves to be transmitted, and for restoring, at the receiving station, said binary signals. Characterized by that it includes fully integrated common main circuits in order to carry out, alternatively, at the transmission station, the conversion of the binary signal, and at the reception station, the aforementioned restoration.
