敏感元件在有线电视器件中的应用

The Application of Sensitive Devices in the Fields of CATV Instruments

阐述敏感元件的基本概念及其在有线电视网络器件中的几种典型应用,首先介绍敏感材料的基本类型和今后的发展趋势,然后详细介绍目前比较典型的几种敏感元件在开关稳压电源、Cable Modem、双向放大器、彩电消磁、程控交换机、光工作站中的应用。

Explain the basic concept of sensitive devices and several typical application. Firstly introduce basic type and tendency of sensitive devices explain the working theory of temperature sensitive resistor, voltage sensitive resistor, humidity sensitive resistor, and the optical signal to electricity converter. Combing these theory, illustrate their practical use in CATV amplifiers, cablemodems, colour TV degauss, switching power supplys, and optical working stations. Also foresee the potential ability of sensitive devices and the future tendency in many professinal applications.
