Hi All, I would like to know the physical meaning of wavelet energy and wavelet entropy. For example I have a one dimensional signal and when I use wenergy, it gives me a certain number, what does this number represent? Any help would be appereciated. Regards, Debela

The energy points out the strength of the signal because it gives the area under the curve of power at any interval of time.
Relative Wavelet energy gives the relative energy in each freq sub-band.
Shannon entropy was proposed to quantify the energy distribution in wavelet sub-band.
