Hi Magnus,
What was the outcome ? Did it work, and what were the constraints or
problems encountered ?
Cheers
Simon

Tom,
I think I wrote some VHDL code for a project like this... if I should
dig it out again?
Cheers,

Hi Simon,
Some additional info. I first heard about the D-FF method of
frequency comparison in the late 90's (from Rick Hambly, I think) on
the old gps mailing list. It sounded really interesting. Since then,
the subject has turned up every few years on this list. But each
time, the topic seems to go away quietly with little or no data,
plots or explanation. In addition, none of the commercial products
I've taken apart appear to use this approach. Hmm. So that begs the
question -- what's really going on, and why.
I'm enjoying this thread because you've shown both technical
competence and optimistic persistence. Perhaps once and for all, with
your efforts, we can settle this matter. You will either find a
working combination with excellent performance, or you will uncover
enough uncontrolled variables that you never want to try it again.
Either way, we all learn a lot. Keep the photos, data, and plots coming.
Thanks,
