Abstract
A technique for amplitude modulating a carrier without producing side-bands is disclosed. In a preferred embodiment, a signal carrier is directly modulated and no energy side-bands are produced. This is accomplished by amplitude quantizing the data or information to be transmitted at the carrier rate or frequency and then resetting the amplitude of the carrier during one of the two 0-crossing times for each cycle of the carrier.
