本文讨论了数字式PAL解码器中一行延迟线的群延迟时间的误差。利用色差信号U,V和N,L之间的转换关系,可以十分简单而理想地解决这个问题。
This article discusses the error of the group delay time for a line of delay lines in a digital PAL decoder. By using the conversion relation between the color difference signals U, V and N, L, this problem can be solved very simply and ideally.
