摘　　要：声卡作为一个输入输出设备,除了能播放声音,还可以用作波形显示的采集端和信号发生器直接产生方波、正弦波和三角波,因而在测量和控制上有着广泛的应用前景。介绍了用VC++实现声卡示波器的方法,并给出了关键行代码。Sound card, as an input and output device, not only can it play a wave file, but also can act as a terminal of collecting wave data and a wave product which can produce squad wave and sine wave and so on, so it will have some function in measure and control field. The method of realizing virtual sound card oscillograph with VC ＋ ＋ is introduced and key codes are provided.
