【摘要】 利用NI Multisim10.1软件对高频电子线路同步检波器进行了仿真分析,测试了调幅信号的输出波形和检波后的波形变化规律;观察并分析了电路中关键节点的频谱关系,得到的虚拟仿真结果与理论分析是相一致的。将该软件合理地应用到高频电子线路实验教学中,可将一些抽象的高频电路的理论教学变得简单明了。把虚拟仿真技术引入到电类课程教学是教学发展的必然趋势,为实验室的开放教学提供一种行之有效的解决方案。更多还原

【Abstract】 This article simulates and analyses the synchronous detection in high frequency electronic circuit by NI Multisim10.1software,tests the wave change law of the amplitude modulation signal and detection signal by building synchronous detection simulation circuit.This article also observes and analyses the distribution of the key node spectrum.The obtained results of software simulation and theoretical analysis are consistent.It is discovered that some abstract high-frequency electronic circuits teaching can become simple and clear,when applying the software reasonably in high frequency electronic circuit experimental teaching.At the same time the obtained virtual simulation technology is introduced to the electricity class teaching,which is the inevitable trend of teaching development.Finally,this article provides an effective solution for opening teaching of the laboratory.更多还原
