摘要
随着计算机技术的发展,虚拟仪器技术得到了广泛的应用;为了充分利用计算机资源进行数据采集及分析,设计了声卡信号采集及分析系统。该系统使用虚拟仪器技术,实现实时声音信号的采集、存储及对信号的谱分析和结果显示。该系统利用pc机上的声卡,具有成本低、使用方便灵活等特点。
With the development of computers technology, the application of virtual instrument becomes more and more widely. The system was designed for sound card signal acquisition and analysis through computer. By using the technology of Labview , the system could realize real-time sound signal acquisition, data memory, and spectral analysis and display the result. This system had used the sound card of pc, had characters of low-cost, convenient and flexible in use.
