Abstract
An apparatus and a method with which a more-precise indication of an rpm is possible even if a position signal continues to be absent. To that end, a counter state of a counter is evaluated and is set to zero at each position signal. If the expected position signal remains absent for an overly long time, an rpm is estimated on the basis of the counter state of the counter. In this way, an rpm change can rapidly be detected and compensated for.
