Abstract

Double sideband suppressed carrier (DSB) signals used to carry AM (amplitude modulation) are usually received synchronously, e.g., with a phase coherent local oscillator maintained at a proper phase so that the contributions of the upper and lower sidebands to the demodulated output are maximized.
