And once you have filled a few seconds into the buffer, you can multiply each of the 1000 locations with a n*sine and n*cosine, and sum the results and you have a phase vector for the signal at n KHz. For signals like DCF77 on half kHz grid, you need a 2 msec = 2000 samples long buffer. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | 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 -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
