一、电视实验的教学内容及教学目的电视实验在电视原理课的教学中起着举足轻重的作用。电视实验包括黑白电视实验和彩电实验两大部分。黑白电视实验一般应用比较流行的μ PC三片机芯,完成以下七个实验:高频头实验、图象中频实验、伴音电路和电源电路实验、场扫描与同步分离电路实验、行扫描与AFC电视实验、视频放大器与显象管附属电路实验、总机调试等。彩电实验:PAL_D解码器实验、基色矩阵电路实验、开关电源实验,这几部分也是彩电区别与黑白电视之所在。在完成以上基本实验的基础上,应尽量创造条件,组织学生组装电视整机,效果
First, the TV experiment teaching content and teaching purposes TV experiment in the teaching of TV principle plays a decisive role. TV experiments include black and white TV experiments and color TV experiments two parts. Black-and-white TV experiment is generally applied the more popular μ PC three-piece movement, the completion of the following seven experiments: tuner experiments, image IF experiments, audio and power circuit experiments, field scanning and synchronization circuit separation experiments, line scanning and AFC TV experiment, video amplifier and CRT pilot circuit, switchboard debugging. TV experiment: PAL_D decoder experiment, primary color matrix circuit experiments, switching power supply experiments, these areas are also the difference between TV and black and white TV where. On the basis of completing the above basic experiments, we should try our best to create the conditions, organize the students to assemble the TV machine, the effect
