摘要
给出了一种电视信号监测板的设计方案,以该监测板为核心可以组成有线电视信号实时监测系统。利用监测板可以从射频信号中提取含增补频道在内的任意频道的视频信号,并对图像和声音信号进行实时监测,在图像、声音信号异常时给出指示。
In this paper,the design of a kind of TV signal monitoring board which acts as a core element in real time CATV signal monitoring system is given.The board can pick any channel from RF signal including supplementary channels,monitor picture signal and sound signal,and give indication when picture signal or sound signal is abnormal.
