I would also like to add that the jitter on the 1PPS from the GPS (aka: The hanging bridge) actually helps measurement precision in exactly the same way systematic jitter makes life better a lot of other places, from tape recording (bias = jitter) to machine tools. The best way to use the sawtooth correction is to apply it in software after all the hardware measurements had their errors smoothed out by it. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
