摘　　要：在ＰＡＬ－Ｄ制彩色电视解码电路存在多种误差参量的条件下，对现有的４种类型测试信号的输出进行了分析和比较，并给出对应测量和调整步骤，结果表明，隔行色度信号是目前从电路角度测量和调整ＰＡＬ－Ｄ制彩色电视解码电路最有效的信号。Under the condition of some error parameters existing in PAL-D color TV decoding circuit, outputs of the four types of test signals are analysed and compared, and the procedures of measurement and adjustment are described in this paper. The results show that line interleaved chrominance signals are most useful to measure and adjust the decoding circuit, and are worthy to be developed and applied as soon as possible.
