摘要
频率合成器是从一个或多个参考频率中产生多种频率的器件。他在信息通信方面得到了广泛地应用 ,并有新的发展。本文主要介绍新型数字化可编程频率合成器 (DDS)的原理。
The frequency synthesizer is a device used to produce multi frequencyfrom one or more reference frequencies?It got the extensive application in the aspects of information corresponding,also new development?This text will introduce us a new digitize programmable frequency synthesizer with its principle?character and the application in transmission measurement
