Vestigial Sideband (VSB) Modulation - Electronics Coach

WebThis means that insofar as the transmission of information is concerned, only one sideband is necessary, and if the carrier and the other sidebands are suppressed at the transmitter, … WebSince these two sidebands carry redundant information, removing one of them will not affect signal transmission. Single-sideband optical signals occupy narrower spectral bandwidth and thus result in better bandwidth efficiency in multiwavelength WDM systems. Also, optical signals with narrower spectral bandwidth suffer less from chromatic ...
