Abstract
A first sensor signal and a second sensor signal are provided by a sensor unit to an evaluation unit. The first sensor signal is dependent on the angular position, and the second sensor signal is phase-shifted by 90° with respect to the first sensor signal. A noise value that is superimposed on each sensor signal due to noise in the corresponding sensor signal is determined by the evaluation unit. Each sensor signal is corrected by the evaluation unit based on the noise value determined for the corresponding sensor signal. Highest amplitudes for each of the first and second sensor signals are determined by the evaluation unit as a maximum value of amplitudes of the respective sensor signals detected over multiple revolutions of the rotational element. An angular position of a rotational component is determined by the evaluation unit based on output from an atan 2-function that takes the first and second sensor signals and the highest amplitudes as input.
