Abstract

PURPOSE:To give control not only to the delay phase degree of a wire section between master station and a slave station but also the delay phase degree of a transmitter of the slave station, by carrying out a communication between the master station and the slave station with a specified pattern signal. CONSTITUTION:A specified pattern signal I0 transmitted from a master station 1 is received at a slave station 2 via a radio circuit and then supplied directly to the delay phase degree measuring part 5 in the station 1. Then the same signal is sent to the station 2 from the station 1 via a wire circuit 23. The station 2 transmits the signal to the radio circuit through a transmitter 4. This signal is received by a receiver 6 in the station 2 and then sent to the station 1 via a wire circuit 22. the delay phase degree can be detected from the difference between the first route 9 and the next route 10. The station 2 is defined as the reference station to detect the delay phase degree of a slave station 3. Phase control is given based on the detected delay phase degree and so as to secure a synchronism of the circuit.
