sampling loop

常见例句

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.
爲計算機控制提供理論指導的是採樣控制理論，而採樣控制器設計是採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.
鎖相環是一種相位自動控制系統，它由鋻相器、環路濾波器、分頻器和壓控振蕩器等部分搆成。取樣鋻相鎖相環採用無源模擬高頻鋻相，除了成本較低的優勢之外，天生具有相位噪聲較小的優點。
