Abstract
An upper and lower side-band generator comprised of a combination of combinational logic circuits. In a preferred embodiment the invention utilizes a substantially square wave sync output associated with carrier and modulator signal generators. A lower side-band signal is generated by synchronizing the transitions of a modulator signal with the transitions of a carrier signal, mixing the synchronized signal with the carrier signal, and filtering the resulting mixed signal. An upper side band signal is generated by synchronizing the carrier and modulator signals, delaying the resulting synchronized signal, and mixing the delayed, synchronized signal and the carrier signal.
