AM electromagnetic waves: 20 KHz modulation frequency on an astronomically-low carrier frequency

I have a very weird question about electromagnetic radiation, carriers, and modulators. Is it mathematically-possible to carry a modulator signal [in this case, a pure-sine-wave-tone] with a frequency of 20 KHz and an amplitude of 1-watt-per-meter-squared on a AM carrier signal whose The fact that you specified the modulation in W/M^2 immediately says you don't know WTF you are talking about and the question is meaningless. You can AM modulate any frequency 0 Fc infinity with any other frequency 0 Fm infinity. Whether it's physically possible or results in massive distortion is a separate issue. snip inane crap -- Jim Pennino Remove .spam.sux to reply. |
