The design of wavelet digital filter and its application intanδ measuring

XING Ya-zhou~1,JIANG Wen-ke~1,ZHANG Mei~1,LI Tie-zhu~2(1.Artifical Intelligence Research Center, Agricultural University of Hebei, Baoding 071001, China;2.Traffic Transportion Administration Section, Traffic Bureau of Baoding, Baoding 071000, China)  
When measuring the dielectric loss factor tanδ, the measuring precision is not contented by using the harmonic analysis method based on FFT (Fast Fourier Transform) because of the electromagnetic interference. The system included a digital filter utilizing the multi resolution character of the wavelet analysis based on the Mallat method. A optimized base of wavelet is selected after the mathematical analysis and the decomposing number is also discussed. The simulation result is given in Matlab.
