Once you get to third-order PLLs you need to start paying serious attention to rounding errors. In most cases using a "double" floating point format will do, but you have to make sure you don't loose precision to normalisation in your additions. I've had varying degress of success myself, and overall I'm not sure it really makes sense to fight the battles, unless you need really long hold-over times. -- 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.
