    應是 Lumped system, 與 Distributed system

    電路系統對輸入訊號的反應與電路實際有效尺寸 十分相關

    Lumped system 內所有的電路與元件對輸入訊號的反應 一致

    Distributed system 內所有的電路與元件對輸入訊號的反應 不一致

    訊號上升長度 L,

    輸入訊號上升時間 Tr, (ps)

    輸入訊號於電路中之延遲時間, D ,(ps/in)

    L= Tr/D

    電路實際有效尺寸 > L/6 者 為 Distributed system , 否則為Lumped system .
