Description: Compared with the standard Fourier transform, wavelet analysis using the wavelet function has not unique, ie wavelet function with diversity. Wavelet analysis in engineering applications, a very important issue is the optimal choice of wavelet problem because different wavelets analysis of the same problem will produce different results. At present we are mainly through the error processing results with the theoretical results signal using wavelet analysis method to determine the quality of wavelets, which determines the wavelets. Haar wavelets have used wavelet, Daubechies (dbN) wavelet, Mexican Hat (mexh) wavelet, Morlet wavelet, Meyer wavelet five species.
