Abstract

Det er beskrevet en fremgangsmåte og en anordning for filtrering av data innsamlet ved et antall diskrete datapunkter, ved å anvende trinnene med å definere et filter som har definerte filterverdier ved definerte filterpunkter som i det minste delvis ikke er sammenfallende med datapunktene, og å bruke de definerte filterverdiene ved de definerte filterpunktene til å bestemme filterverdier ved datapunktene, for derved å korrigere filteret til å ha filterverdier ved filterpunktene som er sammenfallende med datapunktene og å filtrere dataene ved å bruke det korrigerte filteret.
