  • Circuit for processing the output signal from a resistive analog sensor, in particular for the fuel gauge of a motor vehicle, and systems fitted therewith
    Patent number: 5519397
    Abstract: The present invention relates to a circuit for processing the output signal from a resistive analog sensor, comprising firstly a digital filter, and secondly a module forming a digital-to-impedance converter, which filter and module are interposed in series between the output of the sensor and the input of an associated load, the digital-to-impedance converter presenting an output impedance that is variable as a function of the output signal from the digital filter, which is equivalent to the output resistance of the sensor.
