For voice, the max frequency is something like 4KHz (eg telephone quality) which is 250us (125us sampling) .
Telephone quality is 3.1 kHz bandwidth from 300Hz to 3.4kHz, which allows for channel filters/realisable anti-aliasing filters.
I believe that proper NBFM signals should have a 2.8kHz cut off. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
