ABSTRACT
This paper presents a novel method of phonocardiogram acquisition, recording and analysis. The PC/laptop is a host of software that provide complete analysis of heart sounds. Different signal processing techniques such as filtering, wavelet analysis, and spectrum are used to analyse the various components of heart sound.
