This circuit is intended to eliminate the stray signals induced simultaneously on the two conductors of a transmission medium L, one of whose conductors transmits a useful signal. It includes an amplifier 1, R with very low impedance input (-) coupled to one of the two conductors of the medium L and a current generator T, D, Rb, Rc coupled to the other conductor of the medium in such a way that the stray signals in the medium produce currents of like amplitudes and of opposite phases on the low impedance input. Thus, only the useful signal is present at the output VS of the amplifier 1, R. Application to the transporting of signals in a disturbed environment. <IMAGE>
