Abstract: | Adopting the lifting scheme, introduced by Sweldens, a new wavelet is constructed. It overcomes the shortcoming of the classical
wavelets that has no flexibility in the number of vanishing moment. Two examples are given to prove the second-generation
wavelets's potentialities in the singularity detection of signal: a wavelet with vanishing moment and symmetry can be constructed
according to the problem.
