摘　　要：在电子测量和自动化控制领域,虚拟仪器技术取得了巨大的发展。同时传统的信号发生器的设计大多采用嵌入式处理器直接来实现。从探索研究的角度出发,介绍了LabVIEW技术以及用该技术实现虚拟信号发生的硬件与软件设计。该系统通过单片机作为主控芯片,基于LabVIEW来实现虚拟信号发生,完成了正余弦和方波信号发生器的信号系统,然后对该虚拟信号发生器的输出信号进行了实测和分析,并与实际信号比较,进行了理论分析和实验验证。Nowadays, in the electronic measurement and automatic control fields, virtual instrument technology has made tremendous development. At the same time, the traditional signal generator design uses embedded processor to realize directly. This author from exploration research＇ s angle, introducing LabVIEW technology to realize a virtual signal design of the hardware and the software. The system takes the single chip as microcomputer , based on the LabVIEW development to achieve this virtual signal, has completed the cosine square --wave signal generator and signal systems, then has measured and analyzed the signal generator＇ s output signal, compared with the actual signal, finally carried on the theoretical analysis and the experimental verification to the result.
