PROBLEM TO BE SOLVED: To control phase differences so as to be corrected by reproducing a phase again in a transmitter, on the basis of a phase reproduced according to a reference phase in a receiver and comparing the reproduced phase again with the reference phase in the case of operating the transmitter and the receiver which are subjected to communication connection, according to the reference phase. SOLUTION: In a phase control system 100, when the reference phase ϕ0 in a device 1A is inputted to a driver D1 through a phase control circuit C1, the phase ϕ0 is inputted to the receiver R1 of a device 1B via a transmission line L1, and a reproduced reproduction phase ϕ0' is outputted. When a reproduced phase ϕ0' is inputted to a driver D2, a phase ϕ1' is inputted to a receiver R2 of the device 1A through a transmission line L2, and a reproduced reproduction phase ϕ1 that is reproduced again is outputted. When the phase ϕ0 and the phase ϕ1 are inputted to a phase comparator P1, the comparator P1 compares the inputted phases with each other, a calculated phase difference is inputted to the circuit C1 and is controlled. |
