1. An angle sensor apparatus, comprising:
a sensor device that is configured to respond to a rotational movement of a rotatable object by providing at least two phase-shifted measurement signals,
an angle determination device that is configured to take the at least two phase-shifted measurement signals as a basis for determining an angular position of the rotatable object, and
a difference calculation device that is configured to determine a difference between the angular position determined by the angle determination device and an output from a counter,
the counter being configured to be controlled based on the difference between the angular position determined by the angle determination device and the output from the counter.
