  • Electronic interrogation circuits
    Patent number: 5014050
    Abstract: The invention relates to an electronic circuit for remote interrogation of a receiver through a two wire line and to detect the response signals emitted by this receiver. The circuit comprises means for comparing with a reference voltage the actual voltage defining said response signals. This reference voltage is a weighted variable voltage obtained by low band-pass filtering, in a resistance-capacity circuit, of said actual voltage.
