摘　　要：为便于学生对于射频知识的理解,提高学生的实践能力,基于Multisim设计了振幅调制解调仿真实验。以MC1496芯片为核心器件的调制解调仿真实验为例,从理论公式的推导到仿真电路参数的调试验收进行了科学合理的安排,使大多数学生能够将课堂理论知识应用到实际中,并通过最后的电路调试,培养学生发现错误及修正错误的能力,积累系统调试经验。In order to facilitate students＇ understanding of radio frequency knowledge and improve their practical ability,a simulation experiment on the amplitude modulation and demodulation is designed on the basis of Multisim.By taking the modulation and demodulation simulation experiment which has the MC1496 chip as the core component as an example,a scientific and reasonable arrangement from the deduction of the theoretical formula to the debugging and acceptance of the simulation circuit parameters is carried out,which enables the most students to apply the classroom theoretical knowledge to practice.Through the final circuit debugging,students＇ ability is trained to find errors and correct errors,and their experience in the system debugging is accumulated.
