摘要

Disclosed is a multiplexer-demultiplexer provided with: a phase difference detector that detects the phase difference from the reference frequency of a multiplexed signal and the reference frequency of each input/output system; an interpolator that, for the two-way digital signals of each input/output system, obtains two-way digital signals for each input/output system sampled at the reference frequency of the multiplexed signal, by interpolating signals delayed by an amount corresponding to the phase difference of each input/output system, based on the phase differences detected by the phase difference detector; and a signal multiplexer-demultiplexer that multiplexes and demultiplexes the two-way digital signals for each input/output system using the reference frequency of the multiplexed signal.
