Abstract

PURPOSE: To enable the detection good in the identification, by transmitting the transmission end transmission pulse at the transmission device and the receiving end response pulse at the receiving end device through the provision of gate so that the pulse can be synchronized with the time point of zero phase detection of the induction current of the transmission line.
CONSTITUTION: The original impulse required is produced from the transmission end, it is received at the receiving end 2' and the response signal is transmitted from the receiving end device 2' to the transmission end device 2, at the same time when the polarity of pulse current is judged. The induction current is caught with the detectors 3, 3', and the waveform is shaped into the control signal and the original impulse is transmitted when this induction current is zero of the vicinity. Since the detection at the receiving end is made at the zero phase of the induction current inevitably by adding the impulse in synchronizing with the zero phase, the identification of arrival pulse can be easy.
