亮度延迟线用于彩色电视机的亮度通道,其作用是将亮度信号延迟0.5～0.7μs,使其与色度信号同时到达显像管,以避免出现色镶边现象。亮度延迟线的电路符号见图1。 亮度延迟线的种类 彩电中使用的亮度延迟线主要有集中参数型和分布参数型两种。集中参数型延迟线实际上是一
Brightness delay line for the color TV brightness channel, its role is to delay the luminance signal 0.5 ~ 0.7μs, so that it reached the tube with the chrominance signal at the same time to avoid the appearance of color flanger. Luminance delay line circuit symbols shown in Figure 1. Brightness delay line types Brightness delay lines used in color TV are mainly centralized parameter type and distributed parameter type two. The concentrated parametric delay line is actually one
