Abstract
A directional separator-coupler circuit is provided for a medium-frequency carrier current on an electrical line of a low-voltage alternating current network. The separator-coupler circuit comprises a parallel resonant circuit (C,L) inserted into the electrical line and a circuit (E) for the transmission-reception of the carrier currents which are voltage-coupled to the resonant circuit by a connecting circuit (D). The connecting circuit also comprises a series connecting branch (L.sub.d, C.sub.d) which enables current coupling of the transmission-reception circuit (E) and the medium-frequency line, as well as decoupling thereof.
