The ultimate measure of quality in video systems is largely determined by visually looking at the resulting picture. But it is also very beneficial to have objective measurements for judging quality. Of all the electrical measurements for video, differential gain (dG) and differential phase (dP) are often the best for determining the quality of the system. This article will help the reader understand the relationship between the dG/dP measured values and their impact on the video picture’s quality.
