Patent ID: 7403759

Claim:
A method for eliminating interference in measuring signals (S M ) which are corrupted by pulsed interference signals (S ST ), the method comprising the step of providing the measuring signals having a known or determinable interference pulse interval (T St ), whereby the detection period (Δt E ) of an individual measured value (E) is shorter than an interference pulse period (Δt St ), and a plurality of individual measured values (E) is detected at freely selectable time intervals (T E )of the measuring signal (S M ), wherein at least three consecutive individual measured values (E) are detected at time intervals (T E ) that differ from the interference pulse interval (T St ), and an interference-filtered measured quantity (M) is determined with the at least three measured values (E), further including the step of determining which of the individual measured value or values (E) differs most from a remaining portion of the individual measured values, wherein the remaining portion of the individual measured values include at least half of all individual measured values, wherein the individual measured value or values that differ from the at least half of all individual measured values are sorted out, and wherein the measured quantity (M) is determined with the mean of the individual measured values that are not sorted out.
