摘要
为了提高高频电子线路课程的教学质量,把电路仿真软件Multisim 11用于教学实践,设计实现了平衡调幅电路、乘积型同步检波电路、调频信号产生电路及锁相环鉴频电路。基于采样点数、最高显示频率及频率分辨率的关系,确定了频谱分析仪的默认采样频率,并给出清晰的测试点频谱图。在教学实践中,通过对仿真电路的理论分析和生动直观地展现仿真结果,不仅使学生加深了对理论知识的理解,还有助于提高学生的电路设计能力。
In order to improve the teaching quality of high-frequency electronic circuit course, the balance amplitude modulation circuit, synchronous detection circuit, frequency modulation circuit and phase-locked frequency discriminator are designed in combination with the circuit simulation software Multisirn 11. Based on the relationship of the number of the sampling points, the highest frequency and the frequency resolution, the default sampling frequency of the spectrum analyzer is determined. The clear spectral analysis charts for the testing points are provided. In teaching practice, both the analysis of circuits and the intuitive simulation results may help students not only understanding the theoretical knowledge further, but also improving their circuit design ability.
