Class Information
Number: 455/202
Name: Telecommunications > Receiver or analog modulated signal frequency converter > Suppressed carrier
Description: Subject matter relating to a receiver system adapted to derive an output voltage representative of useful information modulated upon a carrier wave in the form of amplitude modulation, the carrier portion of the resultant wave being reduced in amplitude at the transmitter with only one or both of the sideband signals being transmitted to the receiver.
