Abstract

PURPOSE:To shorten the interval between transmission and reception transmitting codes by decreasing influence caused by waveform distortion, by sending the transmission transmitting path codes by using an intermittent control signal during transmission period of two-way transmission and by adding the reception transmitting path code by using the intermittent control signal during the receiving period to a inverse conversion circuit. CONSTITUTION:A transmission signal sent from a transmisstion signal generating circuit 1 is converted into transmission path code (a) such as bipolars by using a conversion circuit 2. This code (a) is added to an end switch circuit 9 which grounds one end of a terminal resistor 4 during the period of disconnection of the resistor 4 and a transmission path circuit 3 by passing through the circuit 3. Furthermore, a reception switch circuit 5 which is continued only during reception is installed and a receiving transmission path code is inversely converted into the transmission signal and the same kind of codes. An intermittent control signal (b) of the circuit 3 and an interminttent control signal (c) of the circuit 5 are generated in a pulse generation circuit 7. The intermittent control signal (b) is added to the circuit 9 by reversing in a reversing circuit 8 and the code (a) is transmitted by the control signal (b) only during transmitting period. The receiving path code is outputted by the signal (c) only during receiving period.
