Abstract

PURPOSE:To enable to reduce the transmission band of transmission signal and to make effective use of the balance cable in existence, the transmitting digital signal pulse on some lines separating in timing. CONSTITUTION:In the switch circuit 2, and in synchronizing with the clock of the digital signal pulse train 1 from the clock generation circuit 3, the input side is sequentially selected to n pairs of balance cables 41-4n every one clock mechanically and electronically. Accordingly, the pulse train 1 is sequentially distributed to n pairs of balance cables 41-4n to be pulse trains 51-5n. These pulse tranis 51- 5n are propagated in the balance cables 41-4n, and inputted to the phase adjuster 6, and after correcting the difference of the respective delay amount, they are synthesized into one pulse train again with the signal adder 7. Since the signals 51- 5n propagated in the balance cables 41-4n actually is the pick up of the pulse train 1 of original signal every other n-1 clocks, the repetitive frequency is 1/n and the signal band is compressed into about 1/n.
