Abstract

Abstract PURPOSE:To suppress the jitter of reproduced digital information by setting the reception system between a master station and a corresponding slave station in an optimum state by the slave station indentification signal before comunication is carried out between the master station and plural slave stations. CONSTITUTION:A master station transmits a carrier wave containing a station indentification signal fB which displays a specific slave station, e.g., station B to all slave stations with a frequency f1 for a fixed period of time while it has no communication with any slave station. The station B detects the signal fB through a BPF and actuates a signal control circuit SC with the detection signal. Then the station B turns on the transmission system and transmits the non-modulated wave of a frequency f2 to the master station. Receiving the non- modulated wave, the master station waits after setting the own reception system in an optimum state.
