現代的電子設計和芯片制造技術正在飛速發展，電子產品的復雜度、時鐘和總線頻率等等都呈快速上升趨勢，但系統的電壓卻不斷在減小，所有的這一切加上產品投放市場的時間要求給設計師帶來了前所未有的巨大壓力。要想保證產品的一次性成功就必須能預見設計中可能出現的各種問題，并及時給出合理的解決方案，對于高速的數字電路來說，最令人頭大的莫過于如何確保瞬時跳變的數字信號通過較長的一段傳輸線，還能完整地被接收，并保證良好的電磁兼容性，這就是目前頗受關注的信號完整性（SI）問題。本章就是圍繞信號完整性的問題，讓大家對高速電路有個基本的認識，并介紹一些相關的基本概念。

自回歸功率譜密度（AR-PSD）方法的基礎是生物組織的離散散射體模型〔超聲體模〕理論，該模型認為生物組織為半規則的散射體分布的，這種方法是基于溫度和頻移的相關特性。本文介紹超聲回波信號對HIFU（High Intensity Focused Ultrasound）治療的測溫技術，從測溫模型和算法，實驗儀器的設計和構建，仿真和離體實驗中獲取了一套有效的測溫方法，利用Matlab7.1和VC++6.0作為工具對超聲回波信號進行計算機仿真，并從實驗獲得的超聲回波信號中分析出具體的溫度變化，驗證了算法的可行性。
