Advantages & Disadvantages of the TPLL Method

I saw that. There is nothing I can do about it other than by using a url
shortener which I am reluctant to do because of the obfuscation and
potential for abuse.

I assume that by now everyone knows how to deal with these problems, and if
someone does not, now is a good time to brush up...

Tom,

I took the liberty of converting your post into an entry in my
Time-Nuts
Wiki:

ency_m
easurement_methods

Just to let you know that your link got busted by a line-wrap
somewhere so it is not clickable and has to be cut and pasted
into place.

But it could be just the World hating me again :)

Cheers,
Steve

Please note anyone can edit this Wiki or create new pages.

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.

schematics, parts

You can hint to most email clients that you'd like lines unbroken,

This may work...

Steve,

This seems to work with your email client sending and Outlook here receiving
(I received that link unbroken), but the same link I just sent was broken,
so it seems Outlook is doing that on the way out, but not on the way in...

I should have known, Microsoft...

Bottom line, no sure way to fix it, therefore the use of brain matter is
recommended...

Didier
