Abstract

PURPOSE: To realize a low-cost radio communication system in which the frequency is selected so that a simple proportional relation may be set up between the frequencies between the master and slave stations and that the frequency of the slave station may be decided in synchronization with the frequency of the master station.
CONSTITUTION: Master station 1 transmits the signal obtained through multiplication modulation of transmission frequency f0 to slave stations 9, 14, 19 ... by means of the highly stable crystal oscillator. Receivers 10, 15, 20 ... of the slave stations receive the multiple-modulated signals and then transmit them to the master station via transmitter 11, 16 and 21 and with use of the transmission frequencies of k1, f0, k2, f0 ... which feature a fixed proportional relation synchronized with frequency f0 sent from master station 1 in case the transmission signal is sent from the slave station. Master station 1 receives these signals through receivers 3∼5. In case the frequency is changed owing to the interference or the like to other stations, the frequency of the slave station can be changed automatically by just altering frequency f0 of the master station.
