摘要
本文简要说明了ＰＡＬ识别器、消色检波器的工作原理和识别、消色信号产生的方法．通过对消色识别检波器的输出讨论，指出可用计算机来判别供给（Ｒ－Ｙ）、（Ｂ－Ｙ）同步解调器的基准副载波的相位是否正确．
The paper illustrates the operating principle of PAL discrimination signal and colour killer signal. After a discussion of colour killer discrimination detector. It is made clear that computers can be used to determine whether it is correct to supply the reference sub-carrier phase of (R-Y),(B-Y) synchro-demodulator.
