The present invention concerns a method for eliminating interference in
measuring signals (S.sub.M) which are corrupted by pulsed interference
signals (S.sub.ST) having a known or determinable interference pulse
interval (T.sub.St), whereby the detection period (.DELTA.t.sub.E) of an
individual measured value (E) is shorter than an interference pulse
period (.DELTA.t.sub.St), and a plurality of individual measured values
(E) is detected at freely selectable time intervals (T.sub.E) of the
measuring signal (S.sub.M). A reliable elimination of interferences
caused by radio-interference sources transmitting in a pulsed manner is
achieved by detecting at least three consecutive individual measured
values (E) at time intervals (T.sub.E) that differ from the interference
pulse interval (T.sub.St), and by determining an interference-filtered
measured quantity (M) with the at least three individual measured values
(E).
