Abstract

The difference of the properties of the Short Fourier Transform, Continuous Wavelet Transform and AR Spectra Array in time-frequency analysing for heart sound signals are studied and compared here. Some problems for using these methods are discussed. It is concluded that the Continuous Wavelet Transform has the highest property in representing the time-frequency distribution of the heart sound signals among these three methods
