【摘要】：利用Multisim10.1軟件對高頻電路頻率自動跟蹤鎖相環(huán)進行了仿真分析;通過改變電阻大小調(diào)整振蕩波形的脈沖寬度,調(diào)整積分電路的電容大小能找出最佳鎖相范圍的數(shù)值大小,改變電容大小調(diào)整波形是否同步和改變信源的頻率找同步范圍,從而實現(xiàn)頻率自動追蹤。仿真結(jié)果與實際理論相吻合,虛擬仿真實例的結(jié)論證明了將Multisim10.1合理引入到高頻電路實驗教學(xué)后,能將一些抽象、枯燥的電子線路理論教學(xué)變得具體和生動,有利于提高電子線路理論課的教學(xué)質(zhì)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.
