本文利用Labview虚拟仪器平台驱动声卡设计了一种信号发生器，可生成正弦、方波、噪声等多种波形，且可以灵活设置波形参数。整个虚拟信号源功能全面，使用灵活，性价比很高，在要求不高或成本受限的场合具有很好的推广前景。%This paper describes a kind of a signal generator designed by using a sonic card I n virtual Labview technical platform to generate multiple waves such as sine, square and noise waveforms. This virtual signal source features multiple functions, flexible application and high cost-effectiveness. It is of a promotion prospect for applications in conditions with low requirements and cost limitation.
