The Development of the Video Distortion Calibration
摘要
Abstract
In order to calibrate the quantity of video distortion, the process and philosophy of measuring distortions of differential gain Dg and differential phase AP are analyzed. A video distortion standard is developed based on a series video distortion signals which are yielded by the method of digital signal synthesis. The calibration system of the video distortion standard and its evaluation of uncertainty in measurement are described in detail. The video distortion quantity is traced to the voltage standard and phase standard.关键词
