This paper gives the definition of wavelet fractional filter and presents the me thod of constructing wavelets by the fractional filter. This method not only incl udes Daubechies method which is used to construct wavelet by polynomial filter,but also includes the method of the filter of B-spline wavelet which is a special case of the fractional filter.
