Method and device for detecting a signal characteristic of a sensor signal originating from a sensor

A device for detecting a signal characteristic of a sensor signal originating from a sensor, the device comprising:

• a sampling unit configured to sample the sensor signal at a sampling rate to generate sample values;
• a calculation unit configured to calculate a correlation measure for the sensor signal by summing up the absolute differences between two consecutive sample values of a sampling sequence of the sampled sensor signal, wherein the sampling sequence includes a certain number, N, of sample values;
• and
• a determination unit configured to determine a signal characteristic of the sensor signal based on the calculated correlation measure.
