摘　　要：采用虚拟仪器的思想,设计了一种基于声卡的数据采集系统。该采集系统在Lab VIEW程序开发环境下,能够实现声音信号的采集、播放和识别等功能。实验结果表明:系统能够正确采集声音频率范围内的信号,可用于该范围内的一般数据采集与应用。In view of the idea of virtual instrument, this paper designs a data acquisition system based on sound card, which can realize the functions of voice signal acquisition, play and recognition in LabVIEW development environment. The experimental results show that the system can do the signal acquisition correctly within the sound frequency range and can be used for the general data acquisition and application within the range.
