摘要

FIELD: communication. ^ SUBSTANCE: multiplexing/demultiplexind device has the phase difference detection part for detection of phase difference from the reference frequency of multiplexed signal and reference frequency for each of input/output lines, interpolation part for the interpolation in digital transmitted/received signal of each of input/output lines using the signal delayed by time that matches the phase difference for each input/output lines, on the base of the phase difference detected by the part for detection of phase difference in order to get digital transmitted/received signal that is quantized with reference frequency of multiplexed signal for each of input/output lines, and part for multiplexing/demultiplexing of signal for multiplexing/demultiplexing of digital transmitted/received signal of output/input lines using the reference frequency of multiplexed signal. ^ EFFECT: increased efficiency. ^ 22 cl, 13 dwg
