SYNCHRONOUS NETWORK DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a synchronous network device for synchronizing a plurality of transmitting means in a position detection system by a spread spectrum communication system.

SOLUTION: A capacitor having a capacitance that is short-circuiting at the frequency of a reference signal but not short-circuiting at the frequency of a power supply is connected between the distribution lines 11 for feeding power to a plurality of transmitting means 1a and 1b to form a loop transmission line. The reference signal is superposed on the transmission line. Thus, a synchronous network is constituted.
