FIELD: measuring equipment.
SUBSTANCE: invention relates to methods of extracting a useful signal from an input signal containing both a useful component and noise. Essence of the invention consists in the fact that the efficiency of the useful component extraction from the input signal containing the useful component and noise is increased, which are in the same frequency range, due to significant reduction or complete elimination of distortion of the shape of the useful signal simultaneously with increase in the signal-to-noise ratio.
EFFECT: invention can be used in various signal filtering systems under conditions of a priori uncertainty.
