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
