摘　　要：利用Multisim软件对单失谐振幅鉴频电路进行仿真分析,通过改变电路元件参数,对比分析了感性失谐和容性失谐波形的特点,以及二极管包络检波器正常检波情况、惰性失真现象。通过仿真实验,可以生动、直观地展现仿真结果,增强学生的感性认识,加深学生对概念和原理的理解。实践证明,这种教学方法有利于调动学生的学习积极性和主动性,明显改善了教学效果。Based on Multisim simulation software,the single loss of resonance amplitude discriminator circuit is analyzed and simulated,Through continuous change of circuit component parameters,this paper compares and analyses the characteristics of detuning wave,the normal detection,inert distortion phenomenon.The simulation experiments show that the simulation results can intuitively and vividly be emerged,the perceptual knowledge of the students can be enhanced,understanding of students for concepts and principles can be deepened.It is proven through practice that this teaching method is helpful to mobilize the learning initiative enthusiasm of students,and to improve the teaching effect obviously.
