摘要
在示波器的使用实验中,与传统仪器实验相结合通过虚拟示波器进行等振幅下,多种频率比与不同相位差情况的李萨如图形观察实验,可更加直观方便地学习测量正弦振动频率的方法并加深理解互相垂直振动合成理论。将传统仪器实验与虚拟仪器实验相结合的实验教学方法,显著改善了示波器的实验教学效果。
In the experimental teaching process of using oscilloscope,combining traditional experiments,the watching Lissajous figure experiment with different frequency ratio and different phase was operated on invented oscilloscope provided by virtual oscilloscope. Through above technique,students can learn measure sine vibration frequency intuitively and understand the theory of mutually perpendicular vibration synthesis insightfully.The proposed experimental teaching technique combining traditional instrument with virtual instrument experiments can improve the experimental teaching effect of using oscilloscope.
