Abstract
A system for bidirectional signal transmission may comprise a forward data transmission circuit to unidirectionally transmit a first input signal and a backward data transmission circuit to unidirectionally transmit a second input signal. The backward data transmission circuit may comprises a logic circuit to detect a voltage difference over a resistance element in the forward data transmission circuit. When the voltage difference is lower than a threshold value, the logic circuit outputs a first voltage level. When the voltage difference is greater than or equal to a threshold value, the logic circuit outputs a second voltage level different from the first voltage level.
