视频信号级的处理,在显示器再现信息还原中占据十分重要的地位。他将R、G、B模拟信号进行增幅与阔宽,并满足色输出级工作要求。利用行同步脉冲信号实现黑电平钳位、对对比度与亮度的控制。在显像管电路正常工作前提下,确保显示器能够输出亮丽多彩的图文画面。本文叙述,康柏472- The processing of video signal level plays a very important role in the reproduction of display information. He will R, G, B analog signal amplification and widening, and to meet the color output level requirements. The use of line synchronization pulse signal to achieve black-level clamp, the contrast and brightness control. In the tube circuit under the premise of normal work, to ensure that the monitor can output bright and colorful graphic. This article describes the Compaq 472-
