| 摘 要： | 在ＮＴＳＣ和ＰＡＬ制彩色电视接收机中，普遍用ＢＰＦ和ＬＰＦ分离彩色电视信号中的亮度信号和色度信号。这些滤波器降低了彩色电视图象的清晰度。文章提出的几种梳状滤波器（ＣＯＦ）可以用来彻底分离亮度、色度信号而不影响彩色电视系统的高清晰度。

| Abstract: | In NTSC and PAL TV receivers,the total colorplexed video signal is divided into two parts by LPF and BPF. One is Y luminance signal, and the other is C chrominance signal.The filters are responsible for a low resolution of pictures. The paper describes some comb filters (COF). They can completely divide Y(t)and C (t) signals. but will not affect high resolution of pictures. |

| Keywords: | comb filter frequency interlacing resolution |
