The characteristics of the Daubechies wavelet are studied. How to realize the Mallat algorithm and how to calculate the denoising threshold are discussed. A group of new application components on wavelet denoising are developed on JBeam platform. Finally, the components are utilized to denoise the real signal of bench test of automotive with sample cases, and the denoising effect of each Daubechies mother wavelet is analyzed to prove that the most suitable mother wavelet is Db14.
