Interference suppression for measuring signals with periodic wanted signals

Abstract

The invention relates to a method for suppressing the interferences in a measuring signal with a substantially periodic wanted signal. According to the method, first a transformation, preferably a wavelet transformation, of the measuring signal to a summation of aperiodic basic logic functions is carried out, wherein each element of the sum has a coefficient. Those coefficients that exceed a predetermined threshold value are characterized as interference coefficients that are presumably influenced by interferences and the interference coefficients are manipulated to suppress the interferences. The manipulated summation is then retransformed to an interference-suppressed measuring signal. An undisturbed base signal is shown as curve 300 (thin) and the disturbed signal as curve 310 (extra-bold). The curve 320 (bold) shows the signal screened according to the invention, by starting from curve 310 and carrying out the embodiment presented in the invention.
