#24 Question: Morlet wavelet

Dear Wavelet Digest Team,

I am a PhD student at the Federal University of Paraiba, Brazil
and I am working on the application of wavelets for power system transients.
I would like to use the Morlet wavelet for this application.
The Morlet wavelet is:

According to the wavelet literature, this function is a wavelet if
w=5.336. In this case the condition required for wavelets:
is satisfied because the value obtained was 0.0000093.
Recently, a research proposed the following function for power
system transients:
In this case:
I conclude that the function h(t) is not a wavelet. Am I right?
Can I change the parameters of the Morlet wavelet?
I would like to receive some informations about admissibility
condition for wavelets.
I would appreciate any information about these questions.
Thank you.
