Abstract
Various devices, systems and methods are disclosed where a noise signal component of a sensor signal is used to obtain information about a sensor device. A device may include an evaluation circuit that is configured to receive a sensor signal having a noise signal component, and the evaluation circuit is further configured to evaluate the noise signal component to obtain information about a sensor device generating the sensor signal.
