Abstract
A method and a device for correcting for tolerances in a transmitter wheel are described. The transmitter wheel has a plurality of approximately equidistant marks that are scanned by a pickup. The pickup supplies a pulse train on the basis of which measured values are formed, with correction values being determined on the basis of a comparison of the individual measured values with a reference value. The measured values are filtered with at least one first and one second frequency-selective filtering.
