Dirivatives of cardinal B-splines are proved to be dyadic wavelets. Compared with existing derivative wavelets such as Gaussian function-based ones and Mallat s ones, this kind of wavelets is capeble to get a variety of wavelet shapeforms, flwxible to adjust filtering charactertistics and possible tomatch the signal being analyzed better. They can be used for signal analysis, pattern recognition, failure discrimination, datacompression, noise reduction, etc. Their fast transform algorithm is described and filter coefficient formulae are given. Simulation results detecting sharp variations in signals and weak partial discharges (PDs) in extreme strong interference demonstrate the practicability of these wavelets.
