(Shameless plug for my friend Bill Riley and his awesome Stable32 software)
Both TheoH and Theo1 have been easily available in the last few upgrades of Stable32. I believe Bill Riley was coauthor on some of the early papers with David Howe of NIST. Like all stability predictors, use Theo with care. In particular, it can provide a deceptively optimistic prediction of stability if you have a perturbation on a timescale that's comparable to your longest tau. -RL ----------------------- Robert Lutwak Symmetricom - Technology Realization Center [EMAIL PROTECTED] (Business) [EMAIL PROTECTED] (Personal) (978) 232-1461 (Desk) (339) 927-7896 (Mobile) (978) 927-4099 (Facsimile) ----- Original Message ----- From: "Dr Bruce Griffiths" <[EMAIL PROTECTED]> To: "Discussion of precise time and frequency measurement" <time-nuts@febo.com> Sent: Wednesday, December 27, 2006 6:06 PM Subject: [time-nuts] New frequency stability measure > Has anyone used the new frequency stability measure reported in > > http://www.tf.nist.gov/timefreq/general/pdf/2109.pdf > > It allows somewhat quicker determination of long term frequency > stability characteristics than using the Allan variance or its > derivatives. > > Bruce > > _______________________________________________ > time-nuts mailing list > time-nuts@febo.com > https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
