The effect of quantization distortion of the differential gain(DG)and differential phase (DP) in digital color TV systems is analysed. Two cases are taken into account. One is that the sampling frequency and the color subcarrier frequency are non-synchronized and the other is that the sampling frequency is three times the subcarrier frequency. For the former case, exact and approximate formulas for calculating DG are obtained. For the latter case, the influence of sampling phase can easily be seen...

The effect of quantization distortion of the differential gain(DG)and differential phase (DP) in digital color TV systems is analysed. Two cases are taken into account. One is that the sampling frequency and the color subcarrier frequency are non-synchronized and the other is that the sampling frequency is three times the subcarrier frequency. For the former case, exact and approximate formulas for calculating DG are obtained. For the latter case, the influence of sampling phase can easily be seen from the calculated formulas of DG and DP. Methods of reducing measuring error caused by quantization distortion are discussed.

本文分析了数字彩色电视系统中量化失真对微分增益(DG)和微分相位(DP)的影响。考虑了两种情况:其一是取样频率与彩色副载波频率为非同步的,其二是取样频率为副载波频率的三倍。对前一情况,得到了计算DG的精确式和近似式。对后一情况,从所得DG、DP计算式易得知取样脉冲相位的影响。最后讨论了减小量化失真引起测量误差的措施。

In this paper described are the principle of operation of the newly developed JXD-1 borehole color telecision system and its principal uses. The key point of the design of the system is discussed emohatically. The single carrier frequency division type of singletube color camera is analysed. The results of development are given. Finally the applications of the borehole color TV system are istroduced.
