.~.~> Single or vestigial sideband or suppressed carrier
DEFINITION
Classification: 375/300
Amplitude modulation:
(under subclass 295) Subject matter in which the pulses are multiplied with a carrier wave so as to produce and transmit at least one sideband equal to the carrier plus or minus the baseband.
(1) Note. In amplitude modulation the amplitude of the carrier wave does not change. The carrier wave can represent the average amplitude of the envelope and, since this is the same irrespective of the presence or absence of modulation, the carrier wave transmits no information. The information is carried by the sidebands.
