Abstract
Method for processing a measurement signal (x) from a pressure measurement cell in order to generate an output signal (y) with the aid of a filter unit (10), wherein the method involves generating the output signal (y) with the aid of the filter unit (10) by at least reducing, preferably eliminating, a noise signal contained in the measurement signal (x), continuously determining a difference between the measurement signal (x) and the output signal (y), and changing a characteristic of the filter unit (10) as soon as the difference becomes greater than a threshold value, wherein the changed characteristic of the filter unit (10) remains as long as the difference becomes smaller than the threshold value, and wherein the changing of the filter characteristic involves decreasing the reduction in the noise signal present in the measurement signal (x).
