sampling loop

基本解释

Firstly, the basic theory of oscillator and sampling phase-locked loop is introduced.
首先阐述了振荡器的基本理论以及取样锁相环路的工作原理。
This system is based on the closed loop feedback principle, and it adopts a method which combines hardware closed loop with sampling control.
为计算机控制提供理论指导的是采样控制理论，而采样控制器设计是采样控制理论的一个核心问题。
Then we can get a good phase noise performance both near and far from the carry frequency by means of sampling phase locked loop. 100MHz crystal oscillator provides the extra reference signal.
锁相环是一种相位自动控制系统，它由鉴相器、环路滤波器、分频器和压控振荡器等部分构成。取样鉴相锁相环采用无源模拟高频鉴相，除了成本较低的优势之外，天生具有相位噪声较小的优点。
