Hi there Just tried the following: I performed the scalogram (with a Morlet wavelet) of a signal. Then I did the same, but with the hilbert transform of the same signal, which produced a smoother scalogram. I am aware that the analytic signal as the negative frequencies equal to zero. Is there any general advantage of using the analytic signal for scalogram construction? I used cwt from the matlab wavelet toolbox.
