ELECTRICAL SIGNAL SEPARATING DEVICE

摘要

The coupler allows the electrical heating wires for a motor vehicle window also to be used as a radio aerial. The coupler separates the HF signal from the heating current. The DC heating current is applied via an inductive HF-decoupling circuit to the heating wires (3) in the window. The HF signal passes via an LC filter and DC-decoupling capacitor to an HF output terminal. Various configurations may be used incorporating filtering and HF coupling circuits.
