Abstract
A multiplexing/demultiplexing device has a phase difference detection part for detecting a phase difference from a reference frequency of a multiplexed signal and a reference frequency of each of input/output lines, an interpolation part for performing an interpolation on a digital transmitting/receiving signal of each of the input/output lines with a signal delayed by time corresponding to the phase difference for each of the input/output lines based on the phase difference detected by the phase difference detection part to obtain a digital transmitting/receiving signal sampled with the reference frequency of the multiplexed signal for each of the input/output lines, and a signal multiplexing/demultiplexing part for performing a multiplex/demultiplex of the digital transmitting/receiving signals of the input/output lines with use of the reference frequency of the multiplexed signal.
