injection phase locking造句
例句與造句
- Dds is used to achieve fine resolution , while injection phase lock circuit is used to realize low phase noise high performance input reference frequency
Dds用于實(shí)現(xiàn)小步進(jìn),而注入鎖相電路則用來(lái)產(chǎn)生低相噪的高性能參考源。 - Then according to the emphasis of the design , went deeply into the theory of pll frequency synthesizers widely used , described pll ’ s working principle , structure and several types in detail , and made research and analysis of pll frequency synthesizers ’ phase noise , including the effect of the active loop filter on the phase noise , and give some methods to make improvement as well , such as changing loop filter form , reducing divide number , and increase phase detector frequency , etc . then paper introduced the principle character and phase noise analysis of direct digital frequency synthesizer ( dds ) and injection phase lock circuit , which are also important circuits in the design
論文首先對(duì)幾十年頻率合成器的發(fā)展進(jìn)行概述,而后針對(duì)本次設(shè)計(jì)的重點(diǎn),對(duì)應(yīng)用較為廣泛的鎖相頻率合成理論進(jìn)行了深入的探討,詳細(xì)介紹了鎖相環(huán)的工作原理、組成結(jié)構(gòu)和鎖相類型,并對(duì)鎖相頻率合成器的相噪特性進(jìn)行了研究分析,包括有源環(huán)路濾波器對(duì)于相噪的影響,提出了改善相位噪聲的幾點(diǎn)措施:改善環(huán)路形式、降低分頻數(shù)、增大鑒相頻率等。接著介紹了直接數(shù)字頻率合成器( dds )和注入鎖相電路的原理特點(diǎn)以及相噪分析,它們也是本次設(shè)計(jì)的重要電路。 - It's difficult to find injection phase locking in a sentence. 用injection phase locking造句挺難的
