着重阐述在电视通带内混入其它频率分量信号,这些无用的频率分量一经窜入信号处理通道,就将迭加在电视图像信号的一些场或行里,形成网纹干扰,针对这些干扰产生的环节给出相应的处理措施和解决办法.%When other frequency component signals are mixed in the TV passband, and when these unwanted frequency components are channeled into the signal processing channel, they will be superimposed on some fields or rows of the TV image signal to form reticulate interference. Corresponding treatment measures and solutions are given according to the specific links where the interferences generate.
