Abstract

PURPOSE:To ensure easy extension of the service area by giving the signal compounding to the output of the wire signal receiving circuit and the amplifier circuit to transmit it to the wire transmission line and then connecting the new receiving station. CONSTITUTION:Variable gain amplifier circuit 9 controls the amplitude of the demodulated output according to the field intensity of the reception of the radio digital signal and gives signal compounding 10 to the output of amplifier circuit 9 and wire signal receiving circuit 11 which receives the signal from the radio receiving station via the wire transmission line. The output of signal compounding circuit 10 is transmitted to wire transmission line 13', and a new receiving station is connected. Thus, the service area can be extended easily.
