色度信号解调器的调试是较复杂的一个问题，因为要调整的三个参数都会影响输出，要在输出中分别反应这三个量是有一定难度的为了说明这一问题，本文详细地讨论了各参数误差对输出的影响，从而寻找一种信号把三个量分别表示出来，达到了解调副载波初相位，色度信号初相位，色差信号的分离度三个量分别表示，因而减少了调试量，缩短了调试时间，提高了调试的正确度
Chrominance signal demodulator debugging is a more complicated issue, because the three parameters to be adjusted will affect the output, the output in response to these three quantities are a certain degree of difficulty. To illustrate this problem, in detail Discussed the influence of each parameter error on the output, so as to find a signal to represent the three quantities, respectively, to demodulate the initial phase of the subcarrier, the initial phase of the chrominance signal, the resolution of the color difference signal is represented by three quantities, thus reducing The amount of debugging, shorten the debugging time, improve the debugging accuracy
