The inventive device for evaluating the sensor signal includes the
provider for providing the sensor signal, the processor for processing
the sensor signal and for providing an information signal comprising
information regarding the amplitude course of the sensor signal and means
for comparing the sensor signal to a first and a second comparison value,
wherein the first and/or the second comparison value are adjustable based
on the information signal such that a difference between the first and
the second comparison value comprises a non-linear relation to the
amplitude course of the sensor signal.
