PURPOSE:To carry out the transmission and reception of information through a piece of transmission line, by piling both the synchronous signal component and the clock signal component simultaneously onto the transmission line of the information component. CONSTITUTION:The main transmitter 1, the secondary transmitter 2 and the receiver 3 are connected to each other by a piece of transmission line 4. The transmitter 1 contains four information input parts a1-a4; the transmitter 2 has four information input parts b1-b4; and the receiver 3 incorporates eight information output parts Ca1-Ca4 respectively. The pulse of a certain frequency is applied to both the synchronous signal generator 12 and the clock signal generator 13 each. The information inputs a1-a4 are turned into the variation information through the modulation signal generator 15 and then modulated by the modulated signal generator 14 and by the synchronous component with its pulse duration modulated to be sent out to the transmission line 4. Thus the synchronous component can be separated from the received signal at the reception side to realize the transmission and reception of information with a piece of transmission line. |
