Title LabVIEW Signal Express System Analysis
Abstract
This design uses LabVIEW Signal Express3.0 analyzed to detect the signals sent by the digital oscilloscope. Proved LabVIEW Signal Express is an excellent software, can achieve a variety of hardware to complete the task. Labview powerful because we only study the extension of the subroutine call virtual digital oscilloscope and a virtual two-channel spectrum analysis filters . LabVIEW also introduced briefly the principle of virtual instruments, through the LabVIEW virtual instrument panel displayed. This paper outlines the interface and functional design, software architecture and key technology and algorithms, and several other areas, specifically introduced dual-channel spectrum analysis filter design and implementation. Keywords LabVIEW Digital Oscilloscope Dual-channel spectrum filter Virtual Digital Oscilloscope
