The Digital Information Age: An Introduction to Electrical Engineering, 2/e (Paperback)

Roman Kuc

商品描述

THE DIGITAL INFORMATION AGE SECOND EDITION by bestselling author Roman Kuc is designed for students considering electrical engineering as a major, and non-engineering majors interested in understanding digital communication systems. Communication between humans and smart devices takes place through sensors and actuators, with logic circuits manipulating binary data to implement useful tasks. The text then examines the basic problem of communicating audio and video data over a network connecting computers and smart devices. System operation is described from analog-to-digital conversion, signals that encode data, through the processing that extracts data from noise-corrupted signals and error correction techniques, to data packet transmission over wired and wireless networks. Basic topics from probability and digital signal processing are presented as needed and illustrated with relevant examples. Ideas are illustrated and extended by problems and projects completed in Excel, with sophistication that evolves along with the course, starting with spreadsheet formulas and graphs, through macros, to simple Visual Basic for Applications (VBA) programming that produces animations that simulate system operation. The accrued facility with Excel techniques is a course outcome valued by students in all majors.

商品描述(中文翻譯)

《數位資訊時代第二版》是暢銷作家羅曼·庫克(Roman Kuc)為考慮選修電機工程專業的學生以及對了解數位通訊系統感興趣的非工程專業學生所設計的。人類與智能設備之間的通訊是通過感測器和執行器進行的,邏輯電路通過操作二進制數據來實現有用的任務。然後,本書探討了在連接計算機和智能設備的網絡上傳輸音頻和視頻數據的基本問題。從類比到數字轉換、編碼數據的信號,再到從受噪聲干擾的信號中提取數據和錯誤校正技術的處理,以及有線和無線網絡上的數據封包傳輸,系統操作都有所描述。根據需要介紹了概率和數字信號處理的基本主題,並通過相關示例進行了說明。這些想法通過在Excel中完成的問題和項目進行了說明和擴展,隨著課程的進展,從試算表公式和圖表開始,到宏,再到簡單的Visual Basic for Applications(VBA)編程,可以生成模擬系統操作的動畫。學生在各個專業中都非常重視對Excel技巧的掌握。
