摘要
随着电工电子技术的不断发展,人们对频率源的要求越来越高,频率合成技术也跟着不断发展,本文介绍了自频率合成技术理论形成以来的三代发展过程。
With the development of electrical and electronic technology, better and better frequency synthesizers are needed. This leads to continuous development of frequency synthesis technology. The three eras of frequency synthesis technology after the foundation of frequency synthesis theory are introduced.
