现行PAL制中存在的交叉干扰,是把亮度信号作为色度信号进行解调,或者把副载波作为亮度信号取出时产生的。对此,虽然已给亮度信号 Y 分配了较宽的带宽,但其效果并不理想。采取其它措施也没有得到预期效果。如
The crosstalk existing in the existing PAL system is generated when the luminance signal is demodulated as a chrominance signal or the subcarrier is taken out as a luminance signal. In this regard, although the luminance signal Y has been allocated a wide bandwidth, its effect is not satisfactory. Other measures did not achieve the desired results. Such as
