摘要
以调制技术为主线 ,介绍有线电视系统中模拟调制技术、光调制技术和数字调制技术的基本原理。随着有线电视的快速发展 ,调制技术正在经历电到光。
This paper takes modulation technique as main hint,summarizes the essential principle of analogue modulation technology、optical modulation and digital modulation technology.With the development of CATV,the modulation technology is coming through the process of developing continuously and syncretizing completely of electric to optic and analog to digit.
