Class Information
Number: 455/204
Name: Telecommunications > Receiver or analog modulated signal frequency converter > Vestigial sideband
Description: Subject matter relating to a receiver system adapted to derive an output voltage representative of useful information modulated upon a carrier wave, the information having been transmitted via a signal comprising a carrier and one normal sideband the other sideband having been largely but not completely suppressed.
