Abstract

A digital filter is disclosed, which is characterised, in that at least one of the multipliers in sequential multiplication procedures and/or at least one of the adders in sequential adding procedures, may be fed data representing various variables or constants and/or the results from sequential multiplication or adding processes may be differently further processed. Said digital filter may be produced at minimal outlay.
