- Abstract
- Subjective evaluations of four different shapes of random noise ranging from flat to triangular are reported to provide means of evaluating the effectiveness of different methods of specifying and measuring noise on international circuits used to transmit 525-line NTSC color TV signals. The general results indicate that the use of noise weighting is necessary and that a new compromise weighting achieved at a CMTT meeting in 1974 appears to be suitable for measuring noise on all international television transmission circuits regardless of the television standard being used. The effect of this compromise weighting on noise measurements concerned with 525-line signals is much the same as that of the weighting previously specified for use on 525-line systems.
