Nope, not in the way you're hoping. Modulate a carrier Fc > with a frequency Fm, and the first sidebands will be at Fc+Fm and > Fc-Fm, just as would be true with AM. That's the narrowest you can > get. So a higher-frequency modulation signal will result in more distant sidebands than a lower-frequency modulation signal? E.g. a 10,000 Hz tone will result in sidebands further from the base carrier frequency than a 1,000 Hz signal?
