Abstract
In a high frequency interference suppression filter for a circuit to be connected to a conductor, particularly two-wire sensors having at least one inductor in series with the circuit to be protected from interference and having at least one capacitor parallel to this circuit, an ohmic series resistor is provided which is matched to the characteristic impedance of the conductor.
