I even mean a third algorithm...
I am focused more the empirical mode decomposition put forward by
Huang, ... after splitting the signal in IMFs they are individually
analyzed by Hilbert transform, or other time frequency transform of
choice...
Im more looking to EMD, but I just found some matlab c

Unfortunately, there are two different things called Hilbert Transform,

(is that right ?)
I probably got that wron

Hi, Ludwig
I've tried making some different Hilbert transform objects--although my
attempts failed b/c I really didn't understand the calculations well
enough. I was trying to make some that used a 1024-point table based on
Fourier behavior.
However, there's an interesting and useful approximati
I was wondering if somebody made HHT objects in Pd like:
[EMD x], splitting a signal in IMF (intrinsic mode) functions...?
How hard would it be to implement?
Greetings!
