摘要
传统的“高频电子线路”实验教学通常依赖于高频实验箱,但由于受到实验场地、实验学时、模块固定、调试困难等因素的限制,学员通常只能掌握操作技能,而缺乏对电路原理的深入理解。对此,引入Multisim仿真设计软件进行“高频电子线路”实验教学,可以构建一种“虚实结合”的教学模式,即“仿真+实践”。通过利用Multisim软件对二极管包络检波电路进行仿真分析,学员可以观察到正常检波、惰性失真和负峰切割失真等现象。其中,仿真结果与理论分析相符,而实际电路测试结果也与仿真结果一致,实现了理论计算、仿真分析和电路验证的闭环过程,有助于学员深入理解原理知识,培养团队合作精神,并锻炼创新思维能力。
Traditional experimental teaching of“high frequency electronic circuit”usually relies on high-frequency experimental boxes,but due to limitations such as experimental venues,experimental hours,module fixation,and difficulties in debugging,students usually can only master operational skills and lack a deep understanding of circuit principles.Introducing Multisim simulation design software for experimental teaching of“high frequency electronic circuit”can construct a teaching mode that combines virtual and real elements,namely“simulation+practice”.By using Multisim software to simulate and analyze the diode envelope detection circuit,students can observe phenomena such as normal detection,inert distortion,and negative peak cutting distortion.Among them,the simulation results are consistent with the theoretical analysis,and the actual circuit test results are also consistent with the simulation results,achieving a closed-loop process of theoretical calculation,simulation analysis,and circuit verification.This helps students to deeply understand the principle knowledge,cultivate teamwork spirit,and exercise innovative thinking ability.
