Abstract

We report some results on the subjective effect of noise introduced in the received pictures of a PCM system by a binary symmetrical channel. More specifically, such noise was compared with noise introduced by an additive white Gaussian channel to a PAM system. It was found that for high signal-to-noise ratios, the Gaussian noise is more objectionable than the BSC noise, while the reverse is true for low signal-to-noise ratios. The crossover point lies in the range 16–20 dB peak signal-to-noise ratio, and tends to occur at a higher signal-to-noise ratio for a picture containing more details.
