wigner-ville transfrom for time-frequency analysis

[anthony_daclin]

Hi,

Just a short note to ask:

What it the best time-frequency tool available in Scilab?

As far as I know, the best one are probably : wigner ( for Wigner-Ville
transfrom) and mapsound.

I also wonder what type of transform is used in mapsound ?

What type of wigner transform is used in Scilab?

And also if someone have some examples of Wigner-Ville utilisation.

I try to use Wigner-Ville, it works quite well, but when I change the
parameters my curve disappear beacause I do not use it correctly.

Thank you for the interest on my topic.
Regards,

Anthony
