摘要
经分析指出大屏幕PAL制彩电采用梳状滤波的亮、色分离电路,消除了亮度对色度的串扰,但同时由于25Hz半场频的影响并未完全消除色度对亮度的串扰分量。
This paper analyzes a two dimensional comb filter for luminance (Y) and colour (C) signal's split used in the big screen PAL colour TV receiver. It points out that this filter eliminates the luminance (Y) to colour's rosstdlk, but reduces (not eliminates) the colour (C) to luminance (Y)'s crosstali became of an half of field freauencv.
