利用模拟梳状滤波器实现彩色全电视信号中的亮度和色度信号分离

THE SEPARATION OF THE BRIGHT SIGNAL AND THE CHROMA SIGNAL ACCOMPLISHED BY USING COMAB-STATE FILTER

本文论述了利用模拟梳状滤波器分离彩色全电视信号中的亮度信号和色度信号的机理和方法。与目前通用的分离方法相比,得出用梳状滤波器进行亮色信号的分离,可以大大降低亮色互串,提高彩色电视图象的清晰度和视频处理系统的信号质量。

The way to separate the bright from the chroma signal both belonging to the CVBS by using the simple anologue comb-state filter is described. Compared with the traditional scparate methods, this way may improve largely the image definition of the color TV and signal quality of the processing systems of the video-frequency.
