Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 129)


It is used the wavelet transform based on the orthogonal signal analysis to analyze the non-stationary snores signal in this paper. The snoring is an important characteris of upper airway obstruction and a typical inspiratory sound appearing during sleep. The basic theory of the wavelet tranform is described and the effective hardware architecture for collecting the snore signal is proposed. The resulting experimental shows that the characteris of different frequencies of signal and offers value for analyzing the temporal feature of snoring sound in health medical treatment.
