Dear All;
I am trying to estimate the power spectrum of the attached signal but i am not getting the meaningfull spectrum as shown in the attached figue
any idea ? it show the power spectrum is unifrom which is not true

Hi Mustafa,
You signal might be too short, and the spectrum estimator might still be in a transient phase. It would help if you can give more complete reproduction steps, and perhaps attach your signal in a MAT file.

Thank you for your answer
but the signal is not short , actually when i compute power spectrum using filter bank method all power values are zeros but when i used wlech method , i got values !
in fact the power value that i got is very small in watt which looks for me that filter bank attenuates all values , so which parameters should I change to avoid that
