Abstract
A transmission bridge comprising two alternating current circuits having a non-inverting signal input, an inverting signal input and a signal output, the non-inverting signal inputs being coupled to associated connecting terminals for the connection of a subscriber's line, the inverting signal inputs being connected to those terminals to which the non-inverting signal inputs of the other alternating current circuits are coupled, the outputs being coupled to the connecting terminals via supply resistors for preventing the anti-phase signals such as speech signals, present at the terminals, from being attenuated and for attenuating by means of the supply resistors in-phase signals, such as noise signals induced in the subscriber's line, present at the terminals.
