Abstract :
A pseudo-random quantizer has been constructed to operate in a standard 405-line television system using a digital channel of only two bits per sample capacity. The "dirty window" effect on moving pictures of a synchronized dither signal has been converted to noiselike flicker equivalent to 30 dB S/N ratio.
