The measurement of random video interference to monochrome and color television pictures

Results are given of subjective tests designed to determine the importance of random interference in various portions of the video band for monochrome and color pictures. Weighting functions are derived enabling random interference to be measured so that equal measured magnitudes correspond rather uniquely to equal interfering effects, regardless of the frequency composition of the random-type interference affecting the received picture. The monochrome results update information presented approximately 9 years ago. The color results are new.*
