Abstract
Different methods of correcting the low-frequency distortions of pulse-wave signal have been considered. A correction method based on forming a reference signal of adaptive filter and using low-frequency filtering of initial biosignal is proposed. The efficiency of different methods of pulse-wave filtering is investigated under the conditions of exposure to interferences of different intensity. It has been found out that the proposed method of filtering low-frequency interferences makes it possible to obtain the lowest distortions in signal processing as compared to the model signals free from manifestation of distorting effects.
