Abstract

This study proposes a new approach of modelling to estimate the spectrum transition of the nonstationary signals with the use of a linear algorithm without assuming any basic functions. In particular, the spectrum transition constraint is employed. By using this method, spectrum transition is clearly obtained during one beat period. Finally, the method proposed in this study will be used as a tool for noninvasive acoustic diagnosis of heart diseases in the near future.
