SIGNAL-TO-NOISE RATIOS FOR TELEVISION TRANSMISSION

Abstract

The note is concerned with the effects of random noise interference in television transmission systems. Such systems are finding increasing application in surveillance and telefactor systems. Numerous results which have been scattered throughout the literature are collected and unified. Three topics are covered: (1) The calculation of the video signal-to-noise ratio for the commonly used television transmission systems (amplitude and frequency modulation); (2) A summary of the signal-to-noise ratio definitions (including noise weighting standards) currently in use for video transmission and conversion between these definitions; and (3) A brief discussion of the subjective evaluation of television picture quality in terms of signal-to-noise ratio.
