Right.
But , eh , in m  i in my opinion the  the  the instantaneous frequency , the  the  the behavior , eh , was  th it was very interesting. Because I  I saw  eh , how the spectrum  concentrate , eh ,
Oh !
around the  the harmonic. But then when I apply the  the rule , eh , of the  in the   the instantaneous frequency of the ne of the continuous filter in the  the near filter , the  the rule that , eh , people propose in the paper doesn't work. And I don't know why.
