Abstract
A transmitter and a receiver for an unbalanced transmission line are constituted by omitting pulse transformers, but in the transmitter by installing switching circuits (S.sub.1, S.sub.4) directly coupled to the unbalanced transmission line (306 or 306') through respective switching devices (305, 310), and in the receiver by installing a pair of input circuits comprising D.C. isolating capacitors (503, 505) and bias circuits (502, 504) for uninverted and inverted input terminals (+,-), in receiver parts (525, 526) for positive polarity pulses and negative polarity pulses, respctively.
