:详细介绍了基于LabV IEW和Matlab的虚拟信号分析仪的设计过程。该信号分析仪可以完全替代传统意义上的信号分析仪,实现其全部功能,并且具有造价低(只在通用计算机上增加一块数据采集卡) ,使用方便,可实现资源共享,更新换代容易等特点。-: Details LabV IEW and Matlab-based virtual signal analyzer of the design process. The signal analyzer can completely replace the traditional sense of the signal analyzer to achieve its full functionality, and has low cost (only in a general increase in computer data acquisition card), easy to use, can realize the sharing of resources, such as upgrading easy characteristics.
