1、通信电子线路课程设计说明书小功率调幅系统系、部:电气与信息工程系学生姓名:陆诗林指导教师:贾雅琼职称讲师专业:电子信息工程班级:电子0901班完成时间:2011-12-12小功率调幅发射机常用于通信系统和其它无线电系统中,特别是在中短波广播通信的领域里更是得到了广泛应用。原因是调幅发射机实现调幅简便,调制所占的频带窄,并且与之对应的调幅接收设备简单,所以调幅发射机广泛地应用于广播发射。本课设结合Multisim软件来对小功率调幅发射机电路的设计与调试方法进行研究。Multisim软件能实现从电学概念设计到输出物理
2、生产数据,以及这之间的所有分析、验证、和设计数据管理。使用Multisim等计算机软件对产品进行辅助设计在很早以前就已经成为了一种趋势,这类软件的问世也极大地提高了设计人员在机械、电子等行业的产品设计质量与效率。本课题的设计目的是要求掌握最基本的小功率调幅发射系统的设计与安装对各级电路进行详细地探讨,并利用Multisim软件仿真设计了一个小功率调幅发射机。关键词通信;调幅;小功率调幅发射机;振荡电路;调制电路;功率放大器;Multisim仿真ABSTRACTHighFrequencyElectronicCirc
