摘要:
Using a previously proposed quality-grading method, tests have been made of the effect of both flat and triangular random noise on still, monochrome, 625-line pictures typical of scenes in television broadcasting. 50% favourable opinions are obtained with a signal/weighted-noise ratio of 36db and 95% favourable opinions with a ratio of 39db.
