I understand that the wavelet scalogram is the square of the magnitude of the output from the dyadic wavelet transform. However, this does not seem to be comparable to the spectrogram calculated by the STFT spectrogram when analysing the same signal. Is there a way to convert the wavelet scalogram so that it gives a good estimation of power, comparable to the STFT? Does this have anything to do with the 'Global wavelet transform'?
I would really appreciate the help with this one! Thanks, Moshe.
