Overtone is a musical term and it is not the same as harmonic. An harmonic frequency is N times the fundamental, where as an overtone merely holds a rational relationship to the fundamental (3/2, 4/3 etc.) The reason you can tell the difference between a violin and a clarinet is that they have different overtone spectra. A somewhat arbitrary subset of an intruments overtones are called "formants" because they are the principal "formers" of the instruments sound. >synchronous >1) happening, existing or arising at precisely the same time >2a) going on or operating together at exactly the same rate > b) recurring together >3) involving or indicating synchronism >4) in physics, having the same period or having the same period and phase Close, but no cigar. If they merely have the same period/frequency, they are "syntonous", but if the phase is also coincident, they are synchronous. >asynchronous >not synchronous, proceeding at its own pace; But just because two signals are asynchronous, doesn't mean they cannot have the same frequency or phase for a shorter or longer period of time, it just means that there is no mechanism that makes it so. >The "asynchronous" serial line is actually anisochronous BTW. No, each transmitter and receiver are anisochronous, but the communication between them, and by language extension the actual cable, is asynchronous. -- 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] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
