Hello everyone!
I wrote proc for Spectral density estimation using Welch's method.

And I want to understand wich fuction is better for computation of Cross-correlation: SignalProcessing:-CrossCorrelation or Statistics:-CrossCorrelation?

Here is my programm with simple signal exmaples:

P.S. (7 hours after initial question) I've just found several mistakes in my PSDw-proc in overlapping.

So, I uploaded new version of my programm. But now I'm not sure in unit of measurement  of power spectral density, but algorithm works correctly.
