摘要
运用LabVIEW开发系统,用普通的计算机声卡代替商用数据采集卡,设计了一个简单的虚拟示波器。该系统能够正确采集声卡设计频率范围内的信号,可以实现基本示波器的测量功能和频谱分析功能。
In this paper, a virtual oscilloscope based on PC sound card and LabVIEW programming environment was designed. The system can acquire signals in the frequency range designed for sound card accurately, and has the function of measurement and spectral analysis.
