Abstract :
This paper describes signal preprocessing of photoplethysmograph record on hardware platform. The constructed device includes basic signal measurement, low-pass and high-pass filtration. The filters are realized by second order Butterworth filters and they are describes by transfer functions. All measurement contains frequency analysis for verification of frequency distortion.
