Beschreibung
Zusammenfassung:	A method for determining a rotational frequency of a wheel, in particular of a motor vehicle, uses a rate of rotation sensor that has a rotary sensor assigned to the wheel and a sensor element assigned to the rotary sensor. The rotary sensor has pulse generators that are arranged in a manner distributed over its circumference and spaced evenly from one another and whose edges are recorded by the sensor element so as to determine the rotational frequency of the rotary sensor. There is provision to use an optimal filter in order to compensate a modulation caused by an eccentricity, and to adapt modulation parameters of the optimal filter through a sequential least-squares method. A time-equidistant frequency signal is subjected to short-term averaging, for example using a PT1 filter, and the modulation is modelled as sinusoidal interference and compensated.
