摘要
对传统弦振动实验进行改进,利用LabVIEW的图形化程序设计及数据采集卡的LabVIEW函数调用,编写LabVIEW程序控制采集弦振动信号的数据采集卡,实现弦振动信号的计算机显示,并通过编写LabVIEW程序进行傅里叶变换频谱分析.
LabVIEW and data acquisition instrument. （）wing to the advantages of GUI nal of string vibration and its FFT frequency （DAQ） card were used to improve the string vibration design and function calls of DAQ, the time-domain sig- analysis result were displayed on a computer.
