Data on Random-Noise Requirements for Theater Television
Pierre Mertz · Journal of the Society of Motion Picture and Television Engineers · 1951
Provisional evaluation of permissible random noise for theater television is considered from several sources of information. These cover broadcast television experience and the graininess in motion picture film; the requirements deduced from the various sources generally agree. For broadcast television, a frequency weighting and limit on weighted noise power have been used. The finer picture detail of theater television presumes a lower permissible random noise. Changes in weighting curve are discussed. A limit figure of noise is suggested, which is comparable to graininess effects in motion pictures, though slightly more severe than present published performance on camera tubes.
