Analysis of breath sounds using higher-order spectra
Main Article Content
Abstract
The basic properties of the Higher-Order Spectra and the possibility of application it to he analysis of respiratory sound is considered. Breathing sounds were analyzed by calculating the cumulants of third order. It is shown that the investigated sounds from the analysis on the basis of the spectra of higher orders may be attributed to a class of respiratory sounds. It is shown that this approach is more effective than traditional ways of solving this problem
