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。
The analysis shows that large-screen PAL color TV comb filter using bright, color separation circuit to eliminate the crosstalk of the luminance of the color, but at the same time due to the impact of 25Hz half-time frequency does not completely eliminate the crosstalk component of the luminance of the color.
