Abstract

PURPOSE:To perform reception bringing the transmission and reception terminals of an insulating transformer under short control while sending the pulse signal of a bipolar signal by turns between stations circuit-connected under the control over the transmission and reception terminals of the insulating transformer without using a hybrid circuit. CONSTITUTION:To send out signal (b) against clock signal (a), bipolar signal (c) is generated through drive operations of driver circuits 12 and 13 by coder 11. At this time, transmission-reception change-over circuit 14 applies, on the basis of the clock signal, driver circuits 12 and 13 with a transmission-reception change- over signal of half the pulse width of signal (d). Only during transmission time T, the bipolar signal is sent via transmission line 5. With transmission delay T4, it is received by terminal station 2. The received signal is detected by positive-polarity- pulse detection circuit 27 and negative-polarity-pulse detection circuit 28 as shown by (e) and (f). On the basis of signals (e) and (f), a synchronizing signal is regenerated and then applied to decoder 31.
