基于LabVIEW的声卡信号发生器设计

Design of Signal Generation System Based on Lab VIEW and Sound Card

研究基于LabVIEW的信号产生系统,利用普通的计算机声卡代替价格昂贵的商用数据采集卡来产生通用的信号,基于LabVIEW开发系统,设计了一个简单的音频信号发生系统,该系统能够正确产生一系列信号波形,诸如正弦波,方波,还有一些特定公式的波形。

This paper introduces a signal generation system based on LabVIEW.Using ordinary sound card of computer instead of the expensive commercial data acquisition card to generate universal signal,it designs a simple audio signal generation system based on LabVIEW development system.The system can produce a series of signal waveform correctly,such as sine wave,square wave,and some specific formula of the waveform.
