This dissertation only considers the signal ’ s distortion by interconnect, such as delay, reflection, discontinuity of microstrip, crosstalk and simultaneous switching noise, and so on. nowadays, there are some simulation software in pcb level, but they are lack of the well ability of modeling. in order to simulate the interconnect accurately, we have to make use of three - dimension full wave analysis method, whose disadvantage is low speed in computing, but is competent for developing rules in high - speed designs
目前也有一些針對這些噪聲的高速pcb板級模擬軟體，但它們都缺乏詳盡的建模能力，特別是當頻率逐漸提高和電路板日益復雜后，更是顯得無能為力，要精確地對互連結構進行分析，三維全波模擬器似乎不可缺少，其缺點就是速度慢，對整板模擬很難實現，但非常適用於規則開發，而這正好是本文除了建模與模擬方法研究外另一個重點。 -

For recent years, adsl has world widely employed and widely used in many aspects such as vod, remote medical treatment and e - shopping etc. but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals, and the adsl ' s frequency rang is from 0 to 1. 104mhz, so we must confront the signal attenuation, the loop line noise impairments, the crosstalk interferences, the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks
近幾年來， adsl在世界范圍內得到充分的使用，廣泛應用於視頻點播、遠程醫療、網上購物等各個方面。但是由於電話線網路是專門為傳輸低頻信號而設計，而adsl的頻譜范圍在0 1 . 104mhz內，因此在傳輸adsl信號時，面臨著信號衰減、線路噪聲、串音干擾、橋接抽頭反射和射頻干擾等等多方面的問題，這就要求在adsl開通之前對線路進行一系列的測試。 -
