Filter arrangement for generating an estimate of a measured variable influenced by disturbances
First Claim
1. Filter arrangement for generating an estimate of a measured variable influenced by disturbances by means of a filter effecting a weighting of measuring signals comprising means (50) for achieving a measure of the disturbance and means (52) for changing the weighting of the measuring signal in dependence on the measure of the disturbance.

Abstract
A filter arrangement for generating an estimate of a measured variable influenced by disturbances, by means of a filter effecting a weighting of measuring signals characterized by means (50) for achieving a measure of the disturbance and means (52) for changing the weighting of the measuring signal in dependence on the measure of the disturbance. In this way, values of the measured variable which appear during the occurrence of the disturbance are not considered with the filtering or are considered with less weighting. In a tape-suspended restrained meridian gyro a characteristic oscillation of the system serves as the measure for the disturbance.
