Abstract :
The concept of linear chroma distortion permits us to express in numbers the subjective quality of the color in a TV picture. The MOD 12.5T pulse is the signal with which these distortions can be measured. The MOD 12.5T pulse, with its composition and frequency spectrum, is presented, together with measurement methods for the relative chroma level (RCL) and the relative chroma time (RCT).
