  • System and method for narrow bandwidth amplitude modulation
    Publication number: 20060109061
    Abstract: A method and system for narrow band amplitude modulation in which audio is sampled periodically and held constant except during brief periods which are close to zero crossings of the carrier signal comprising an RF sine wave. The result is a modulated signal with sidebands of reduced amplitude. Without sidebands, the modulated RF sine wave may thus be very narrow banded, allowing many more stations to fit within the same band.
