For what I read Windowing the data introduces errors. Can anyone clarify me please what correction should I do (if any is needed) to calculate the psd and the power (see SpectrumType below) using the pwelch function.
What I have done:
N = length(Ydata);
nfft = Npoints;
SpectrumType = 'psd';
Noverlap = ;
[Pxx,f] = pwelch(Ydata,wlen,Noverlap,nfft,Fs,SpectrumType);
If any correction is needed can you provide me please the correcttion values for this windows.
