No Signal | TV Static Noise | White Noise 4K | Analog Noise | Flicker

No Signal | TV Static Noise | White Noise 4K | Analog Noise . Noise, in analog video and television, is a random dot pixel pattern of static displayed when no transmission signal is obtained by the antenna receiver of TV sets and other display devices. The random pattern superimposed on the picture, visible as a random flicker of "dots" is the result of electronic noise and radiated electromagnetic noise accidentally picked up by the antenna. This effect is most commonly seen with analog TV sets or blank VHS tapes.
