... because of the better frequency selectivity of the CB filters for the case with higher support length of the wavelet. The higher support length of the optimal wavelet is also associated with higher ... spread of wavelet in time. This definition of time-duration gives a measure of time localization of the wavelet [25]. Now, the above definition of time duration is used for s...
