Which is it? That's easy! The first harmonic of a 20KHz wave is 20KHz. Wm Leler p.s. Remember the "crucify a cute critter" contest? Who needs a cute critter? I propose a monthly "fry a low flying flamer" contest. Any nominations for the initial award :-?

The first harmonic of a 20KHz wave is 20KHz. ^^^^^ ^^^^^^^^ ^^ ^^^^^ ^^ ^^^^^ > Wm Leler I was going to stay out of this but I couldn't resist pointing out the technical faux pas committed by so many of our elite staff of engineering types, and I'm glad someone besides myself caught this. The fundamental frequency is xHz. Harmonics are multiples of this frequency. The first harmonic is by definition the fundamental (xHz times 1 is always xHz) but it's more commonly referred to as the fundamental. The first harmonic that's not also the fundamental is the 2nd harmonic. Most people, however, incorrectly refer to this frequency as the first harmonic. Let's see now, if xHz is 20,000 Hz, then 2 times xHz is 40,000 Hz or 40KHz, at least it was the last time I heard. Can we move on now? I don't think anything's been left out. Maybe we should move this discussion to net.religion or net.flame. As for the awards, we all make mistakes (even tpyographical ones:-). Maybe this calls for a new newsgroup, net.audio.awards?
