摘要： A method for processing a time discrete, one dimensional, measurement signal. The method includes the step of applying to the sequence a recursive filter having a variable recursion coefficient (K(n)), wherein the recursive filter is embodied in such a manner that, in each case, the output, measured value (y(n)) obtained for a measured value (x(n)) is obtainable by subtracting a preceding output, measured value (y(n−1)) from such measured value (x(n)), by multiplying the obtained difference value (d(n)) with a recursion coefficient (K(n)) associated with such measured value (x(n)) and by adding the obtained product to the preceding output, measured value (y(n−1)). For determining the recursion coefficient (K(n)) associated with a measured value (x(n)), a predetermined function (Klin(da)) rising at least sectionally with the magnitude of the difference value (da) is applied to the magnitude (da(n)) of the difference value (d(n)) obtained for such measured value and the obtained function value (Klin(n)) is applied recursion coefficient (K(n)) as corresponding to such measured value x(n), at least when the function value (Klin(n)) is greater than or equal to the recursion coefficient associated with the preceding measured value (K(n−1)).
