摘要
利用Multisim10.1软件对抗载波双边带调幅电路的仿真分析,观察双边带(DSB)调幅波的波形变化规律,采用虚拟频谱仪的曲线分析了载波和上下边频的频率及电压增益,结果与理论分析吻合。通过实例验证了合理地将Multisim10.1引入高频电路实验教学后,可将抽象、枯燥的高频电路理论教学变得具体和生动,有利于提高高频电子线路理论课的教学质量。
The resist carrier wave double sideband amplitude modulation circuit is analyzed and simulated by Multisim 10.1 software.The law of double sideband amplitude modulation waveform is observed,and the frequency and voltage gain of the carrier wave and the upper and lower sideband by spectrum analyzer＇s curve are analyzed.The result is good in accordance with theory.By using actual example after reasonable utilization Multisim 10.1 in the experimental teaching of High Frequency Electronic Circuit,it is shown the simulation technology could make Abstract theoretical teaching become concrete and lively,thus facilitating improving teaching quality of High Frequency Electronic Circuit course.
