為了提高數字水印抗擊各種圖像攻擊的性能和保持圖像的穩健性和不可見性,提出了一種基于離散小波變換(DWT),SVD(singular value decomposition)奇異值分解水印圖像和原始載體圖像的離散余弦變換(DCT)的自適應水印嵌入算法,主要是將水印圖像的兩次小波變換后的低頻分量潛入到原始圖像分塊經過SVD分解的S分量矩陣中,同時根據圖像的JPEG壓縮比的不同計算各個圖像塊的水印調節因子。實驗證明該算法在抗擊JPEG壓縮、中值濾波、加噪等均具有很好的魯棒性,嵌入后的圖像的PSNR達到38,具有良好的視覺掩蔽性

在本課題中,兼顧了效率及線性度,采用自適應預失真前饋復合線性化系統來改善高功率放大器的線性度。由于加入自適應控制模塊,射頻電路不受溫度、時漂、輸入功率等的影響,可始終處于較佳工作狀態,這使得整個放大系統更為實用,也更具有拓展價值。

負反饋放大電路之所以能夠產生自激振蕩,是因為在放大電路中存在 RC 環節。于是在放大電路的高頻或低頻段會產生附加相移DjAF ,如DjAF的足夠大,使負反饋變成正反饋。

第四章 信號分離電路 第四章 信號分離電路第一節 濾波器的基本知識一、濾波器的功能和類型1、功能:濾波器是具有頻率選擇作用的電路或運算處理系統,具有濾除噪聲和分離各種不同信號的功能。2、類型:按處理信號形式分:模擬濾波器和數字濾波器按功能分:低通、高通、帶通、帶阻按電路組成分:LC無源、RC無源、由特殊元件構成的無源濾波器、RC有源濾波器按傳遞函數的微分方程階數分:一階、二階、高階第一節 濾波器的基本知識 第一節 濾波器的基本知識二、模擬濾波器的傳遞函數與頻率特性(一)模擬濾波器的傳遞函數模擬濾波電路的特性可由傳遞函數來描述。傳遞函數是輸出與輸入信號電壓或電流拉氏變換之比。經分析,任意個互相隔離的線性網絡級聯后,總的傳遞函數等于各網絡傳遞函數的乘積。這樣,任何復雜的濾波網絡,可由若干簡單的一階與二階濾波電路級聯構成。 第一節 濾波器的基本知識(二)模擬濾波器的頻率特性模擬濾波器的傳遞函數H(s)表達了濾波器的輸入與輸出間的傳遞關系。若濾波器的輸入信號Ui是角頻率為w的單位信號,濾波器的輸出Uo(jw)=H(jw)表達了在單位信號輸入情況下的輸出信號隨頻率變化的關系,稱為濾波器的頻率特性函數,簡稱頻率特性。頻率特性H(jw)是一個復函數,其幅值A(w)稱為幅頻特性,其幅角∮(w)表示輸出信號的相位相對于輸入信號相位的變化,稱為相頻特性。

高速數字系統設計下載pdf:High-Speed Digital SystemDesign—A Handbook ofInterconnect Theory and DesignPracticesStephen H. HallGarrett W. HallJames A. McCallA Wiley-Interscience Publication JOHN WILEY & SONS, INC.New York • Chichester • Weinheim • Brisbane • Singapore • TorontoCopyright © 2000 by John Wiley & Sons, Inc.speeddigital systems at the platform level. The book walks the reader through everyrequired concept, from basic transmission line theory to digital timing analysis, high-speedmeasurement techniques, as well as many other topics. In doing so, a unique balancebetween theory and practical applications is achieved that will allow the reader not only tounderstand the nature of the problem, but also provide practical guidance to the solution.The level of theoretical understanding is such that the reader will be equipped to see beyondthe immediate practical application and solve problems not contained within these pages.Much of the information in this book has not been needed in past digital designs but isabsolutely necessary today. Most of the information covered here is not covered in standardcollege curricula, at least not in its focus on digital design, which is arguably one of the mostsignificant industries in electrical engineering.The focus of this book is on the design of robust high-volume, high-speed digital productssuch as computer systems, with particular attention paid to computer busses. However, thetheory presented is applicable to any high-speed digital system. All of the techniquescovered in this book have been applied in industry to actual digital products that have beensuccessfully produced and sold in high volume.Practicing engineers and graduate and undergraduate students who have completed basicelectromagnetic or microwave design classes are equipped to fully comprehend the theorypresented in this book. At a practical level, however, basic circuit theory is all thebackground required to apply the formulas in this book.
