The wavelet transform and its applications to phonocardiogram signal analysis.

L Khadra1, M Matalgah, B el-Asir, S Mawagdeh.   

Abstract

The wavelet transform, which is the decomposition of a signal into a set of independent frequency channels, is shown to be a useful diagnostic tool in the analysis of heartbeat sounds. In particular, the wavelet transform enables the experimentalist to obtain qualitative and quantitative measurements of time-frequency characteristics of phonocardiogram (PCG) signals.
