摘要
利用虚拟仪器开发平台LabVIEW和数据采集卡PCI-6024E设计了一种新型虚拟多功能数字示波器.它不但具有现代示波器的功能,还实现了数字滤波和频谱分析等新功能,文中重点设计了IIR和FIR两种数字滤波器,来满足不同数据处理的要求,该虚拟示波器有较强的实用价值.
Based on the software LabVIEW of virtual instrument and data acquisition card PCI -6024E, a kind of virtual multi - functions Digital Storage Oscilloscope is designed in the paper. This virtual scope not only has the functions of the modem scope, but also realizes some expanded functions including digital filter, requency response analysis and so on. IIR and FIR were designed emphatically to fulfill the request of data processing. So the virtual oscilloscope has practical value.
