【Abstract】 This paper has Provided the calculational method for spectrum of yarn signal using continuous wavelet transform, and constructed wavelet function adapting to calculation of spectrum for yarn. If spectrum is calculated with such method in this paper, then number of channel can be chosen according to demand, and correspondingly spectrum of three dimensions can be got.更多还原
