Abstract: Although much information is available about the random noise visibility in various television systems, none refers to the interpretation of the results in terms of the particular television standard. The author assumed a linear summation on noise visibility of the individual frequency component of the noise spectra, and concluded that the video weighting function in different television standards must be identical except that its reference frequency is varied in proportion to the line frequency. The validity of the analysis was supported by experiments on the relative visibility of the octave-band random noises with twelve television standards including the four different ones now in use.
