sigma phase 中文意思是什麼
sigma phase
解釋
δ相-
Sigma delta modulation frequency synthesis is an advanced technology that applies in pll ( phase - locked loop ) frequency synthesizer, which could transform the spurs created by fractional - n synthesizers into phase noise that could be filtered by inherent low - pass identity in pll
此技術應用-調制將鎖相環頻率合成器中分數分頻器產生的相位雜散轉化為相位噪聲,通過鎖相環本身低通濾波特性濾除,從而使用單環即可獲得很高頻率解析度和極低的相位雜散。
