Information × Registration Number 0206U005235, 0104U002286 , R & D reports Title A new principle design impedance pletysmography devices from a digital signal processing popup.stage_title Head Gavriljuk M., Registration Date 09-03-2006 Organization Lviv Polytechnic National University popup.description2 Created and got subsequent development principles of construction of the rheocanals, which allow to simplify scheme realization, multiply the amount of canals, promote exactness and noise immunity measurings, that it became possible due to digitising of rheosignal after an algorithm sigma-delta of transformation and stage of digital phase-quadrature division. The algorithms of treatment of rheogram of are developed in and frequency and time-frequency region proof to action of technical and biological hindrances (in particular of respiratory), that allows to simplify and unify procedure of determination of characteristic points, and also to promote exactness of determination of physiology parameters.
