    摘要： In a method and a device for checking the adjustment of a plurality of actuators driven by a common drive in different mass flow channels of an internal combustion engine, the actuators are adjusted between a first limit stop and a second limit stop in the particular mass flow channel. The actuators are brought by their common drive to the first limit stop. A first value of a variable that is characteristic of a position of the common drive of the actuators is determined when the first limit stop is reached. The actuators are brought by their common drive to the second limit stop. A second value of the variable that is characteristic of the position of the common drive of the actuators is ascertained upon reaching the second limit stop. A difference is determined between the first value and the second value. The difference is compared in terms of absolute value to at least one predefined threshold value. An error in the adjustment of the actuators in the various mass flow channels is recognized when the absolute value of the difference deviates unacceptably from at least one predefined threshold value.

    摘要： An electronic circuit for detecting measured quantities has a sensor unit for generating an analog measurement signal and a signal detecting unit (120) with a first analog/digital converter for digitizing the analog measurement signal. Differences in the fluctuations of the supply voltages that are supplied to the sensor unit and the signal detecting unit essentially result in the generation of undesirable fluctuations in the measurement signal. To minimize these effects or compensate for them, the digitized measurement signal is corrected In response to a voltage signal (U) that represents the imprecision x1 of the first supply voltage (VS1).
