內容簡介

　　本書是學習電路（該課程是大學工科電類和相近各專業(yè)的共同的技術基礎課）的教科書。此書所選內容均為電路課程的基礎知識，它與當前國內外高校在對該課程內容的取舍上做法大體一致。全書大致分為三部分：（1）直流電路、電路定律、電路元件；（2）交流電路、相量法、電功率、三相電路、頻率響應；（3）拉普拉斯變換、傅里葉變換、雙口網(wǎng)絡。該書在編寫、教學方法上的安排頗有特色：講解明白易懂；有大量的例題、習題；有用電路分析軟件分析電路的內容；每章末有應用實例，幫助讀者認識電路概念的應用。本書還配有學生用CD-ROM（只讀光盤）。該書可供學習電路課的大學生作為教科書使用，亦可供有關技術人員、高校教師參考。
