Abstract

Die Erfindung beschreibt einen Sensor, insbesondere einen Hallsensor, mit einem Sensorelement (1; 10), das ein ein Störsignal (STS) enthaltenes Sensorsignal (SS) abgibt, mit einer Auswerteeinrichtung (6; 20), die mit dem Sensorelement verbunden ist und einen Subtrahierer (2; 21) enthält, der das Störsignal von dem Sensorsignal subtrahiert, wobei der Sensor eine Filtereinrichtung enthält, die das Störsignal aus dem Sensorsignal herausfiltert. Der Sensor und das beanspruchte Verfahren ermöglichen eine Kompensation des Störsignals.
