彩色电视机是将多种复杂电子技术综合运用于一体的一种接收机,由于其电路结构和工作原理复杂,初学者往往不得要领,入门困难。笔者认为,学习《彩色电视机原理》应撇开复杂的电路结构,从彩色全电视信号各成分的组成特点及其分离方法和功能框图两个方面入手,方能抓住主线、层层深入。 一、彩色全电视信号组成的主要特点 Color TV is a kind of receiver that integrates a variety of complex electronic technology into one. Due to the complexity of its circuit structure and working principle, beginners often can not get the essentials. The author believes that the study of “color TV principle” should put aside the complex circuit structure, from the color TV signal components of the composition and characteristics of its separation and functional block diagram from two aspects, to seize the main line, layers of depth. First, the main features of the full color TV signal
