摘要
介绍了一种以普通声卡为硬件设备的虚拟信号发生器的设计方法。设计采用了虚拟仪器技术,利用NI公司的Lab-VIEW软件的模块化编程以及多线程技术,实现了多种常见周期信号及任意指定信号的双通道输出。
This paper presents the design of a virtual signal generator that utilizes a normal PC sound card as hardware device. The generator was developed based on virtual instrument software LabViEW of NI Company.The modularized programming and multithreading technical is performed during the designed process.
