...In [7], it was shown that if the wavelet is chosen as the first derivative of a smoothing function (a function whose FT has energy concentrated at low frequencies) then the local maxima of the absolute value of the D WT indicate the occurrence of sharp signal variations while the local minima indicate the occurrence of slow signal variations, provided the first and second derivatives of the smoothing function exist....
