摘要：PROBLEM TO BE SOLVED: To provide a differential transmission system capable of reducing an influence of noise given to a differential signal. SOLUTION: In the differential transmission system for transmitting the differential signal output from a transmitting end block TB to a receiving end block RB via a cable 10, constant-current sources 11, 12 are connected to the transmitting end side of the transmitting end block TB and the receiving end side of the receiving end block RB, respectively. As the result, since resistance components of the constant-current sources 11, 12 are infinite, common mode noise between the transmitting end block TB and the receiving end block RB is not converted into a normal mode between differential signals.
