XT-14型电视信号发生器的改进

Improvement of the XT-14 TV signal generator

在XT-14型彩色电视信号发生器的电路基础上,增加了U分量逐行倒相、色度逐行倒相、非逐行倒相和隔行色度四种编码方式,给出对应电路和调整方法。改进后电视信号发生器效果良好,具有更为广泛的使用范围。

This paper introduces four kinds of encoding modes ba sed on XT-14 color-TV signal generator's circuits and their adjusting method. Th e four kinds of encoding modes are U-component phase alternation line-by-line co de and chroma phase alternation line-by-line code and non-phase alternation line -by-line code and alternative-line chroma code. The improved color-TV signal gen erator works better and can be used in a more extensive area.
