Method for correcting the measuring sensor signal corrupted by the untrue running of the rotor of an inductive rotational speed measuring sensor

摘要

A description is given of a method for correcting the measuring sensor signal corrupted by the untrue running of the rotor of an inductive rotational speed measuring sensor. For the purpose of correction, use is made of filters whose corner frequencies can be varied, and which are varied by a signal proportional to the frequency of the useful signal.
