SYSTEM FOR RELAYING JJY TIME DATA

摘要

PROBLEM TO BE SOLVED: To stably provide a JJY radio wave transmitting time data even to an underground town or an urban area much in indoor noise shilded with a reinforced concrete building or the like.

SOLUTION: A JJY receiving section 22 sends a modulation signal wave 5 according to information 9 to a CATV by means of a receiving part 6 for JJY radio wave reception and a time information encode part 4 built therein, a carrier wave of 75mhz is FSK-modulated with time information data in a modulator 8 and distributed to each of JJY receiving sections 22 over a private cable network 5. The FSK signal wave received in each of the JJY receiving sections is demodulated by a time information decoder 6 and transmitted to a time information display part 7 as a time information signal 25.
