Abstract

Some results obtained in recording and processing of phonocardiograms are presented herein. To process phonocardiographic signals, a cascade filtration method has been used that allows detecting tones of the cardiovascular system in the background noise. The effectiveness of the proposed processing method is demonstrated by the results of visualization.
