Abstract
A method of displaying phase characteristics of a video signal is employed in a system that determines the phase angle between the color synchronization burst signal and horizontal synchronization pulses of a color video signal. The method includes selecting an image location on a display screen of video monitor and forming at the image location an image representing the value of the phase angle. The image is formed with a length along one axis passing through the image location and with a light intensity. One of the length or the light intensity is proportional to the value of the phase angle to provide an indication of the value.
