Abstract

En fremgangsmåte og et apparat er beskrevet. Apparatet omfatter et lager av minst en historisk følermåling, et lager av potensielle grensefrekvenser og et filter. Hver potensielle grensefrekvens er knyttet til en respektiv potensialforskjell mellom en følermåling og den lagrede historiske følermåling. Filteret har en grensefrekvens som blir dynamisk valgt fra de lagrede, potensielle grensefrekvenser på basis av en forskjell mellom den lagrede, historiske følermåling og en gjeldende følermåling. Fremgangsmåten omfatter å bestemme en forskjell mellom en gjeldende følermåling og en historisk følermåling, og dynamisk å velge en grensefrekvens for et filter for gjeldende følermåling ut fra forskjellen.
