Abstract
PURPOSE:To prevent deterioration of reliability of a signal, which is caused by a transmission loss and a noise, by transmitting a frame consisting of period of 1 bit, address of (m) bits and information of (n) bits, by means of two-phase differential phase-shift keying. CONSTITUTION:The system A is constitute of a master station 100 and slave stations 1-15. The frame consists of a synchronizing bit F=the first bit, address bits m=4 bits, and information bits n=3 bits, and this frame is brought to two-phase differential phase-shift keying and is transmitted. In this way, a signal can be transmitted with high reliability even in case of a transmission line having a large absolute amount of a transmission loss and a noise, such as a distribution line.
