PROBLEM TO BE SOLVED: To enable an adjustment by a large delay amount without degrading an electrical signal even in a redundant system.SOLUTION: A first distributor divides an electrical signal into two paths, one and the other of which are delayed in a first variable delayer and a second variable delayer, respectively, and second and third distributors divide electrical signals output from the first and second variable delayers, respectively, into two paths. A delay amount difference measurer measures a delay amount difference between corresponding electrical signals distributed by the second and third distributors. First and second switches intermit transmission paths of the other electrical signals distributed by the second and third distributors, respectively, and a combiner outputs a combination of the electrical signals passed through the first switch and the second switch, respectively. Delay amounts of the first and second variable delayers are alternately incremented such that the delay amount difference measured by the delay amount difference measurer remains within an allowable range, and the path is interrupted by the first or second switch during the application of the incrementing process. |
