Re: Spectrum Estimate functions

[Sergio Dominguez]

Thanks everyone for your answers,

Actually my question was not so oriented to get the spectrum estimation, but to 
know how to integrate this spectrum in a band of frecuencies to get the 
percentage of the energy contained in that band against the total energy of the 
system.

My problem is that I do not know whether I can just integrate the area below 
the spectrum in that frecuency band due to the fact that the signal has been 
previously windowed-detrend, therefore varying the average energy level.

Would anyone know how to do this?

Thank you very much,

Sergio
