| + | 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. | ||
