电视接收实验设备的设计与实现

Design and Implementation of Television Receiver for Experiment

电视接收机实验是电视原理实验的重要组成部分。在分析比较几种常见的实验用电视接收机设计思路的基础上,根据中国传媒大学电视原理课程特点和实验要求,设计并实现了新的电视接收实验设备。利用该设备所开发的实验与课程重点紧密结合,电路简单,实验原理明确,步骤简洁明了,含盖了电路设计、调试和测试等实验环节。电视接收实验设备的开发填补了国内高校在接收机实验方面的空白。

The television receiver used for experiment is an important part of the television principles. Based on the comparison with several routine de- signs of the television receiver,a new experimental device is designed and implemented. This new device has closely contact with the course. The circuit is simple and the principles are clear. It increases the opportunities for students to deepen their knowledge in practice and understanding. The develop- ment of the TV receiver used for experiment supplies a gap in the field of receiver experiment of universities.
