Wavelet-технологии в аппаратах функциональной диагностики

Abstract

Work is devoted to a substantiation of application of method WAVELET technologies at research of non-stationary signals. The method is based on reception of a dimensionless measure of similarity of the local form of an investigated signal with the form-standard in the form of a sinusoid of the certain frequency by use of algorithms time-frequency of the analysis of the high sanction and methods of partial reconstruction of a signal in phase space. Examples of use of a method of WAVELET-technologies are resulted at processing a reographics, electrocardiographies and phonocardiographies signals.
