The features of continuous wavelet transform for physiological pressure signal

The paper shows the possibility of continuous wavelet transform application for the analysis of pulse model signals. It has been found that wavelet analysis is capable of defining local characteristics of a signal and investigating any changes in the spectral distribution of a pulse signal. The wavelet spectra of pulse signals of healthy people and of people with functional disorders have been investigated. It has been shown that the shape of pulse signals of people with functional disorders is changing, which brings about change in the wavelet spectra. The paper describes a new wavelet-based detection method for physiologic pressure signal components.© (2007) COPYRIGHT SPIE--The International Society for Optical Engineering.
