Well, and bandwidth. A pure sine wave uses, errr, almost zero bandwidth*, whereas one with harmonics needs somewhere to put those. A 500Hz sine wave at 7100kHz is really a sine at 7100.5, whereas a 500Hz sine wave with harmonics at 1000 and 1500 kHz is now using 7100.5, 7101, 7101.5... ... or am I preaching to the choir here? * Yeah, yeah, ok, not quite true as soon as you start modulating it with keying envelopes. -- "Nosey" Nick Waterman, G7RZQ, k2 #5209. #include <stddisclaimer> [EMAIL PROTECTED] It is ten o'clock; do you know where your processes are? _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
