【正文】 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。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。1KHZ的低頻信號為調(diào)制信號。本電路的設(shè)計思路十分清晰，原理較為易懂，結(jié)構(gòu)簡單明了，使用起來方便、穩(wěn)定且實用價值較高。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)計要求及方案選擇 1 1 1 方案1 ....................................................................................................................................1 方案2 ....................................................................................................................................1 方案3 ....................................................................................................................................22 理論分析與設(shè)計 3 3 63 電路設(shè)計 6 硬件電路的設(shè)計 6 7 ....................................................................................................................74 系統(tǒng)測試 8 8 8 105 總結(jié) 11參考文獻(xiàn) 12附錄1 ..........................................................................................................................................13附錄2 ......................................................................................................................................
