在电子技术专业中,《电视机原理》是一门主要的专业课,也是前面所学知识的综合运用,因此电视机的维修技能,是一项综合性的训练课程,对学生在以后从事专业工作起重要的作用,必须在教学的过程中,加强技能的培养。技能的形成是以知识的掌握为基础的。在教学中,必须使学生掌握好方框图、基本原理图、信号流向图、视频信号的组成及一些基本的数据,如场频、行频、定点的波形,特性曲线等。这些是分析故障的基础,为了更好地掌握电视机的工作原理,有必要对不同的机型进行比较分析,使学生能对整机电路进行分析,针对学生的实际情况宜以定性分析为主。
Among the major electronic courses, “Principles of Television sets” is a major specialized course, which is also a comprehensive utilization of the knowledge learned in the past. Therefore, the maintenance skills of television sets are a comprehensive training course that provides students with professional training in the future To play an important role, we must strengthen the training of skills in the teaching process. The formation of skills is based on the mastery of knowledge. In teaching, students must master the block diagram, schematic diagram, signal flow diagram, video signal composition and some basic data, such as field frequency, line frequency, fixed-point waveform, characteristic curve. These are the basis for the analysis of the failure, in order to better grasp the working principle of the TV, it is necessary to comparative analysis of different models so that students can analyze the whole circuit, students should be based on the actual situation of qualitative analysis .
