【 摘 要 】

This article presents some results of processing of phonocardiography signals (PCG signals) for cardiac cycle tone identification under ambient noise of varying intensity. For PCG signal processing, proposed is a refined approach based on active band pass filter bank, which allows improving an accuracy of cardiac cycle tone identification under ambient noise. The efficiency of the application of the proposed approach has been demonstrated by the respective qualitative, quantitative results and experimental data obtained upon processing of PCG signals according to the offered technique. A 3D model of the cardiac cycle tone identification system has been developed based on this conceptual idea.
