摘要
收音机调台原理是电路分析课程中谐振电路的一种典型应用。在此利用LabVIEW软件设计了一个收音机调台原理的演示系统。该系统利用ActiveX控件技术调用WindowsMediaPlayer作为收音机面板,能通过改变谐振电路的参数,实时绘出频响曲线并完成调台操作,具有界面友好和操作简单的特点,可应用于电路分析课程的课堂演示中去。
The radio tuning principle is typical application of the resonant circuit in the circuit analysis course. A radio tun- ing principle demonstration system is designed in this paper by using LabVIEW software. The ActiveX controls is used in the system to call WindowsMediaPlayer as radio panel to plot the frequency response curve in real time and complete the operation of transferring station through changing the parameters of the resonance circuit. The system has the characteristics of friendly in- terface and simple operation. It can be applied to classroom demonstration of circuit analysis course.
