【正文】 《高頻電子線路》 課程設(shè)計(jì)報(bào)告 題 目：幅度調(diào)制電路的設(shè)計(jì) 專 業(yè)：通信工程 年 級：2011級 學(xué) 號：1110618018 學(xué)生姓名： 聯(lián)系電話： 指導(dǎo)老師：王輝 完成日期：2013年 12 月 16 日 摘要在電子科技發(fā)達(dá)的今天，通信和廣播領(lǐng)域也在電氣界中扮演著重要的角色。而通信又成為人們生活、工作當(dāng)中不可或缺的組成部分。為了提高通信質(zhì)量和處理信號方便，需要在將語音、圖象等有用信息經(jīng)過調(diào)幅后再發(fā)送出去，這就無疑需要一種振幅調(diào)制電路來實(shí)現(xiàn)。幅度調(diào)制就是載波的振幅（包絡(luò)）受調(diào)制信號的控制作周期性的變化。本實(shí)驗(yàn)中載波是由晶體振蕩產(chǎn)生的10MHZ高頻信號。1KHZ的低頻信號為調(diào)制信號。振幅調(diào)制器即為產(chǎn)生調(diào)幅信號的裝置。本電路的設(shè)計(jì)思路十分清晰，原理較為易懂，結(jié)構(gòu)簡單明了，使用起來方便、穩(wěn)定且實(shí)用價(jià)值較高。關(guān)鍵詞：高頻，通信，幅度調(diào)制，乘法器 ABSTRACTIn electronic science and technology developed today, munications and radio field also plays an important role in the electrical munication has bee an integral part of people live and order to improve the quality of munication and signal processing is convenient, in the voice, image and other useful information after am sent again, it39。s definitely need an amplitude modulation circuit to modulation is the amplitude of the carrier (envelope) under the control of the modulation signal as the periodic experiment carrier is generated by crystal oscillator 10 MHZ high frequency KHZ low frequency signal for the modulation modulator is an amplitude modulation signal of the thinking is clear, principle of this circuit is relatively straightforward, simple structure, easy to use, stable and higher practical value.Key words：High frequency munication, amplitude modulation, multiplier 目 錄摘 要 IABSTRACT I1 設(shè)計(jì)要求及方案選擇 1 1 1 方案1 ..................................................................................................
