A good glossary would be a big help.

I can't figure out what that means.

I think it's something different than the simple digital sort of things that 
Daniel has been discussing.  Standard deviation makes me think that it's 
interested in the noise of capturing a PPS signal.  If you look carefully, 
you might get a bell curve or something like it, probably not symmetric.

These are my opinions.  I hate spam.
