视频电缆传输中的干扰,是直接影响视频信号质量的重要原因,是视频工程中最棘手的问题。本文分析了视频电缆传输中的两个主要因素:中波电台干扰与50HZ电流干扰,阐述了四种有效抑制干扰的措施。
Video cable transmission in the interference, is a direct impact on the quality of the video signal is an important reason for video engineering is the most difficult problem. This article analyzes two major factors in the video cable transmission: the interference of the radio station in China and the interference of the 50HZ current, and describes four measures to effectively suppress the interference.
