Abstract

Bei einem Verfahren und einer Vorrichtung zur Filterung einer Größe, welche wenigstens ein Filtermittel (225) zur Bildung einer Ausgangsgröße abhängig von einer Eingangsgröße aufweist, wobei das wenigstens eine Filtermittel wenigstens eine verzögernde Wirkung auf die Größe aufweist, und welche wenigstens ein Begrenzermittel (200) zur sich zeitlich ändernden Begrenzung des Maximalwertes der Größe aufweist, ist insbesondere vorgesehen, dass eine Änderung der sich zeitlich ändernden Begrenzung unmittelbar in die Ausgangsgröße eingerechnet wird. Durch diese Maßnahme lassen sich Schleppfehler auch bei der sich ändernden Begrenzung bestmöglich kompensieren.

In a method and apparatus for filtering a size having at least one filter means (225) for forming an output dependent on an input, said at least one filter means having at least a size delaying effect and at least one limiting means (200) to the time-varying limitation of the maximum value of the size, is provided in particular that a change of the time-varying limit is calculated directly into the output variable. As a result of this measure, following errors can be compensated for as best as possible even with the changing limitation.
