Abstract

The subject of the paper is devoted to optoelectronic acquisition and processing of the pulse waveform of arterial blood, which contributes as the major component to peripheral photoplethysmographic signal. Considered questions concern problems with reliable processing of noninvasively acquired biooptical signals that are influenced by noises, artifacts and other disturbances. The proposed procedures of signal conditioning make possible effective acquisition of useful parameters of a raw noisy PPG signal. Novel design of the adherence circuit that allows eliminating the disturbing low-frequency trend has been presented. Results of verifying studies, where real signals acquired with transmission sensor were processed using this and circuit and classical linear circuit, are discussed.
