Abstract

PURPOSE:To enable data transmission without any relay amplifier, by transmitting data signal in assigned time, and amplifying and superimposing the data signal from the synchronizing signal transmitted from the receiver and the data signal from other transmitter, on distribution line, in the time other than assigned time. CONSTITUTION:While the synchronizing signal passing through an AND circuit 32 resets a timing circuit 13, the synchronizing signal is fed to a signal feeding circuit 17, and the output is superimposed on the data signal from other transmitter on the distributing line and delivered to other transmitter. When the synchronizing signal is not received, the timing circuit 13 counts clock signals, and if the address signal from the timing circuit 13 and that from an address set circuit 14 are not in agreement at a coincidence circuit 15, the data signal is fed to the distribution line via the signal feeding circuit 17 for relay amplification.
