商品描述

ABOUT THE BOOK Probability, Random Variables and Random Signal Principles offers clear and concise coverage of theories of probability, random variables, and random signals, including the response of linear networks to random waveforms for the junior-senior level course in electrical engineering. The book offers a careful, logical organization which stresses fundamentals and includes almost 900 student exercises and abundant practical applications for engineers to understand probability concepts. The new edition sought to provide better integration of the material covering continuous and discrete time process, by presenting the material in parallel as much as possible. This should enable the student to better appreciate the similarities and differences between the same concepts when applied to continuous time and discrete time processes. This edition features: Digital Topics: Discussion on the continuous-time and discrete-time is clearly differentiated in Chapter 8. The discrete-time material retains the coverage of sampling theorems (baseband and bandpass) for random processes as a foundation for the DT material. Correlation functions and power spectrums for these processes, which are developed and connected through the sampling theorems and the DT Fourier transforms, are covered in Chapters 7 and 8, with some introduction in sections 6.1-6.3. The structure of linear DT digital systems is developed in both the sequence and transform domains. Problems: End of chapter problems have been combined into a single list with numbering that corresponds to the chapter's section to which the problems mainly apply. Starred sections: The level of coverage of the material is intended for a typical undergraduate program. However a small amount of more advanced material has been scattered throughout the book to serve as stimulation for the more advanced student or for schools using the book at a higher level. These sections are indicated by a star (*). MATLAB-based examples and problems: They have been integrated into the text in key places (indicated by a computer icon). NEW TO THIS EDITION The discussions of complex valued random variables and random processes in Chapters 5-7 have been updated to include a description of the pseudo-variance and pseudo-covariance. Chapter 6 was reorganized to separate the discussions of the concepts of distributions and moments, stationarity, and ergodicity into separate sections, and reordered the presentation. In Chapter 7, the coverage of power spectrum for discrete time processes was brought forward and updated. New examples have also been introduced in Chapters 6 and 7 to better illustrate discrete time processes. Chapter 8 has been restructured to present the introductory concepts of continuous-time and discrete-time linear systems simultaneously. The book has a Companion Website (www.mheducation.asia/olc/peebles) that includes a downloadable version of the solutions manual for students and instructors as well as JPEG files of the book's figures for instructors.

商品描述(中文翻譯)

《概率、隨機變量和隨機信號原理》提供了對概率、隨機變量和隨機信號理論的清晰而簡潔的介紹,包括線性電路對隨機波形的響應,適用於電氣工程高年級學生的課程。該書以細心而有邏輯的組織方式強調基礎知識,並包含近900個學生練習和豐富的實際應用,以幫助工程師理解概率概念。新版力求更好地整合連續時間和離散時間過程的內容,盡可能並行地呈現材料。這樣可以使學生更好地理解在連續時間和離散時間過程中應用相同概念時的相似性和差異性。本版特點如下:數字化主題:在第8章中,對連續時間和離散時間進行了明確區分。離散時間材料保留了對隨機過程的取樣定理(基帶和帶通)的涵蓋,作為離散時間材料的基礎。這些過程的相關函數和功率譜通過取樣定理和離散時間傅立葉變換進行了發展和連接,分別在第7章和第8章中進行了涵蓋,並在第6.1-6.3節中進行了一些介紹。線性離散時間數字系統的結構在序列和變換域中進行了發展。問題:章末問題已合併為一個列表,編號與主要適用於該章節的問題相對應。星號標記的部分:材料的涵蓋水平適用於典型的本科課程。然而,少量更高級的材料已分散在整本書中,以激發更高級的學生或在更高水平使用該書的學校。這些部分以星號(*)標示。基於MATLAB的示例和問題:它們已集成到文本的關鍵位置(以計算機圖標標示)。本版新增內容:第5-7章中關於複數值隨機變量和隨機過程的討論已更新,包括對虛方差和虛協方差的描述。第6章重新組織,將分佈和矩、平穩性和遍歷性的討論分為獨立的部分,並重新排序了演示。在第7章中,將離散時間過程的功率譜的涵蓋範圍提前並進行了更新。還在第6章和第7章引入了新的示例,以更好地說明離散時間過程。第8章已重新結構,同時呈現了連續時間和離散時間線性系統的入門概念。該書還有一個附屬網站(www.mheducation.asia/olc/peebles),其中包括學生和教師可下載的解答手冊以及教師用的圖片的JPEG文件。
