sampling loop

基本解釋

Firstly, the basic theory of oscillator and sampling phase-locked loop is introduced.
首先闡述了振蕩器的基本理論以及取樣鎖相環(huán)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.
為計算機(jī)控制提供理論指導(dǎo)的是采樣控制理論，而采樣控制器設(shè)計是采樣控制理論的一個核心問題。
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.
鎖相環(huán)是一種相位自動控制系統(tǒng)，它由鑒相器、環(huán)路濾波器、分頻器和壓控振蕩器等部分構(gòu)成。取樣鑒相鎖相環(huán)采用無源模擬高頻鑒相，除了成本較低的優(yōu)勢之外，天生具有相位噪聲較小的優(yōu)點。
