一种捷变频调制器的制作

Manufacture of Vary Carrier Frequency Modulator

彩色电视调制器是CATV系统前端的关键设备 ,介绍一种采用专用调制器集成电路与成品高频头改制而成的捷变频调制器 ,其电路简单 ,工作稳定 ,造价低廉 ,适合当前电视“村村通”

Color TV modulator is an important front device for the CATV system. In this paper, we present a method for manufacturing varing carrier frequency modulator by integration of a special IC into a commercial HF head. This kind of modulator is especially suitable for use in the countryside CATV projects because of its simplicity, stability and low-cost.
