Abstract
A data transmission system including a pair of parallel transmission lines, applies data signals to the transmission lines through a transformer and an associated impedance connected across the lines. The transformer is magnetically coupled to at least one of the lines to apply a signal current thereto. The signal current is transferred to the other line through the impedance. The impedance is tuned to the transmission frequency so that it has a very low value during data transmission.
