CATV 系统中交扰调制的特性分析

Analysis about the Characteristic of Cross-coupling Modulation in CATV System

论述了电缆电视系统中交扰调制干扰的严重程度与干扰频道最高输出电平、传送频道数目及级联放大器数量的关系，指出采用混联的方法可适当减少交扰调制干扰．

Systematically reports the relations between the severe interference of cross-coupling modulation and the highest voltage output,and the number of transmission channel and cascade amplifier in CATV system.And also reports the approach of employing mixing on-line to properly reduce the interference of cross-coupling modulation.
