Abstract
A method and an apparatus for tuning a filter is provided wherein the filter has at least one adjustable element for adjusting at least one performance parameter of the filter like for example a cut-off frequency, wherein a pseudo-random test sequence is applied to the filter, wherein the cross-correlation function of the test sequence and the filtered test sequence is calculated, and wherein the at least one adjustable parameter is adjusted until the cross-correlation function at at least one point basically coincides with a corresponding point of a nominal cross-correlation function for the filter.
