Abstract :
The authors would like to thank the discussers for their interest in our paper [1], where the definitions of the power components contained in the IEEE Standard 1459-2000 were reformulated using the discrete wavelet transform (DWT) which is a time-frequency transform that allows preserving both time and frequency information. In [1], five decomposition levels in the DWT tree were selected, leading to six nonuniform frequency bands. The approximation a5 is the scaling level, while the details d5,d4,d3,d2, and d1 are the five wavelet levels.
