如何去正確理解采樣時(shí)鐘抖動(dòng)(Jitter)對(duì)ADC信噪比SNR的影響

前言 :本文我們介紹下ADC采樣時(shí)鐘的抖動(dòng)(Jitter)參數(shù)對(duì)ADC采樣的影響,主要介紹以下內(nèi)容: 時(shí)鐘抖動(dòng)的構(gòu)成 時(shí)鐘抖動(dòng)對(duì)ADC SNR的影響 如何計(jì)算時(shí)鐘抖動(dòng) 如何優(yōu)化時(shí)鐘抖動(dòng) 1.采樣理論

簡(jiǎn)單理解抖動(dòng)Jitter測(cè)量

抖動(dòng)jitter的有關(guān)概念和理論很多,容易把人抖暈;本文目的是幫助產(chǎn)品研發(fā)和測(cè)試工程師,不需要研究時(shí)頻域抖動(dòng)測(cè)量的原理和公式,只講用什么手段測(cè)抖動(dòng),以及測(cè)試值的表達(dá)含義。
