The processing unit (120) has an interface (130) for reading sensor signals (115a, 115b) i.e. transducer signals. The sensor signals represent an identical physical parameter e.g. distance. A sensor signal conditioning unit (140) determining a sensor signal evaluation parameter based on components. The components are formed by signal values of the sensor signals, where the signal values are received at an identical time point. A sensor signal evaluation unit (150) determines the physical parameter based on the sensor signals using the sensor signal evaluation parameter. Independent claims are also included for the following: (1) a sensor unit (2) a method for processing a sensor signal (3) a computer program comprising a program code for execution of a method for processing a sensor signal.
