虚拟仪器技术在高频电路教学中的应用

Application of Virtual Instrument Technology to Lecture of High Frequency Circuits

将基于LabVIEW的虚拟仪器技术引入高频电路教学,利用虚拟仪器在信号处理、分析及显示方面的强大功能,使许多高频电路的基本理论可直观地用图形表达出来,并可生动地验证信号调制等方面的相关理论.同时利用LabVIEW包含的仿真仪器控件,实现了实验教学中的虚拟仪器开发,并用实例说明该方法的可行性.

Based on LabVIEW, this paper introduces the application of Virtual instrumentation to the teaching of high frequency circuits. Using the powerful functions of virtual instrumentation in signal processing, analysis and display, many abstract theoretical principles in high frequency course are readily expressed with the graphic interpretations. Some pertinent theories, such as signal modulation, are impressively verified. By taking advantages of the controls included in LabVIEW, the virtual instruments are developed, and the feasibility is explained using real study-cases.
