4VSB
Type of vestigial sideband modulation
From Wikipedia, the free encyclopedia
4VSB is an abbreviation for 4-level vestigial sideband modulation, a type of radio transmission capable of transmitting two bits of information (22=4) at a time.[1] Other faster but less rugged forms include 8VSB and 16VSB. While 2VSB is more rugged, it is also slower.
