Abstract
A sensor system for providing a main signal and an error signal, comprising: a sensor unit providing a sensor signal; a first signal processor downstream of the sensor unit, adapted for receiving a second signal equal to or derived from a sensor signal, and for performing a first operations on the second signal so as to provide a first processed signal; a second signal processor for receiving the first processed signal and for performing second operations inverse of the first operations, so as to provide a second processed signal; and an evaluation unit for receiving the second signal and the second processed signal, and for evaluating whether the second signal matches the second processed signal within a predefined tolerance margin, and for providing the error signal.
