PROBLEM TO BE SOLVED: To provide a phase controller for efficiently matching phases and performing satisfactory no-hit changeover. SOLUTION: Delay memories M1 and M2 are provided for respective transmission lines A, B and delay received signals P1a, P1b based on a delay amount D. A comparison range setting means 11 sets a range for comparing the phases, and a phase comparison means 12 compares the phases of output signal P2a and P2b from the delay memories M1 and M2 within the range. A phase control means 13 repeatedly sets the delay amount D when as a result of comparison, the phases do not match. |
