摘要
CATV系统发生交扰调制时，为什么会有白色的而不是黑色雨刷状干扰，严重时为什么还会有干扰频道的负像出现。笔者从非线性元件的转移特性出发，分析了电缆电视系统产生交扰调制的原因，并从理论上解释了上述现象。
This article analyses the reason of the generation of cross-modulation in CATV systems, why the appearance of cross-modulation look like white, but not black vertical stripes, and why negative images appear from the interfering channel when cross-modulation is serious. In view of the transfer characteristics of nonlinear devices, a theoretical explanation is provided to the phenomena mentioned above.
