Integral of Power Spectral Density

I am creating a code which analyses an EMG signal which required me to compute the power spectral density. I done this using the spectrum.welch function, but it now required to find the integral of the PSD which is what i have been unable to do. Any help would be greatly appreciated.

Hi,

The avgpower method available with the dspdata object in the Signal Processing Toolbox calculates the integral of the power spectral density. One can visit the documentation link here for more details.

Hope this helps!
