Phase/Frequency Measurement Methods

There was a thread about the Tight PLL method on the Time-Nuts mailing list. One useful outcome was this post by Tom Van Baak:

Here are a couple of really good articles that describe many methods of phase/frequency measurement, including TPLL.
You'll see some nice “advantage/disadvantage” lists in several of these documents, which is why I'm posting the links.

Warren & Bruce, please look at the first five documents at least. John too. Lots of TPLL info. This is all worth reading. I don't know why I didn't find some of these papers six months ago.
