本篇論文主要是在探討時序抖動與信號偏移對於高速序列傳輸電路傳輸品質的影響。 論文中使用統計分析的方法架構出一個以USB 2.0規格為基礎的電路模型,以此來探討時序抖動與信號偏移對USB2.0電路信號傳輸品質的影響。並且更深入的探討時間誤差組成比例的不同所造成的影響。 除此之外,本論文也同時使用位元錯誤率測試(BERT)的方式,來驗證TQ函數的可行性。 This thesis discusses what effect resulted by jitter and skew in transmission quality of high speed serial circuit. In this thesis, we use statistical method to build a circuit model based on USB 2.0 circuit. Use this to discuss jitter and skew what will result in transmission quality of USB 2.0 circuit. Advanced discuss different components of time error will cause what effect. Aside from this, this thesis also uses Bit Error Rate Test method to verify the viability of TQ function.
