【摘要】：利用Multisim10.1软件对高频电路频率自动跟踪锁相环进行了仿真分析;通过改变电阻大小调整振荡波形的脉冲宽度,调整积分电路的电容大小能找出最佳锁相范围的数值大小,改变电容大小调整波形是否同步和改变信源的频率找同步范围,从而实现频率自动追踪。仿真结果与实际理论相吻合,虚拟仿真实例的结论证明了将Multisim10.1合理引入到高频电路实验教学后,能将一些抽象、枯燥的电子线路理论教学变得具体和生动,有利于提高电子线路理论课的教学质量。
[Abstract]:The simulation analysis of the high frequency circuit of automatic frequency tracking phase locked loop using Multisim10.1 software; through the pulse width change resistance to adjust the size of the oscillation waveform, numerical value of capacitance adjusting integral circuit can find out the best lock range, change the capacitance wave adjustment and change the frequency of the source is synchronous for synchronous range, so as to realize automatic frequency tracking. The simulation results are consistent with the actual theory, virtual simulation example proves that Multisim10.1 is introduced into the high-frequency circuit experiment teaching, put some abstract, boring theory teaching electronic circuits become specific and vivid, is conducive to improve the quality of teaching of electronic circuit theory course.
