摘　　要：抽样定理是信息传输技术的重要定理,通常验证该定理的硬件电路固化,缺少分析和设计过程,不利于理解定理的本质内容。基于Multisim仿真平台进行抽样定理的验证电路设计,首先基于信息传输理论进行系统设计,其次对设计出的系统进行仿真,最后对仿真结果进行分析,并结合仿真结果修改系统参数后再次仿真。结果表明这种做法不仅有利于全面理解抽样定理所涉及的相关理论,而且还锻炼了系统分析和设计的能力。Sampling theorem is an important law of information transmission technology. Usually, the hardware circuit to verify the theorem is solidified. The lack of analysis and design process is not conducive to understanding the essence of the theorem. Based on the Multisim simulation platform to design the verification circuit of the sampling theorem, firstly design the system based on the information transmission theory, secondly simulate the designed system, finally analyze the simulation results, and modify the system parameters based on the simulation results and then simulate again. The results show that this approach is not only conducive to a comprehensive understanding of the relevant theories involved in the sampling theorem, but also exercises the ability of system analysis and design.
