摘要
从有线电视系统中交流干扰对终端图像及伴音的影响分析入手,探讨有线电视系统中交流声干扰的形成因素,并对有线电视系统中的载波交流声比进行测量,从而实现对交流声干扰的对抗,提高系统中信号的传输质量。
By analyzing the influence of AC noise to terminal image and sound in cable television system, this paper discusses the formative factors of AC noise and measuring the AC noise ratio of carrier wave in the system. This paper fulfills the task to suppress cable television AC noise and enhances the signal transmission quality.
