摘要： The present invention proposes a sensor apparatus (200) for generating a measurement signal (U a ) based on an input signal (H m ). The input signal is preferably a magnetic field. The sensor apparatus includes a signal generation device (220) and a sensor device (230). The signal generation device (220) generates a periodic signal (H e ) of the same type as the input signal (H m ). The signal generation device further generates a mixed signal based on the input signal (H m ) and the periodic signal (H e ). The sensor device (230) finally generates the measurement signal (U a ) based on the mixed signal and a characteristic curve (110) of the sensor device (230). By mixing the input signal (H m ) with a periodic signal (H e ) of the same type, the sensitivity and robustness of the sensor apparatus (200) can be increased by synchronously reducing its complexity.
