Title LabVIEW Signal Express Analysis System
Abstract The design is based on LabVIEW Signal Express3.0 analysis and simulation of signal detection。Proved LabVIEW Signal Express is a powerful software that enables a variety of hardware to complete the task。Relationship between the time we only study the extension of that subroutine call analysis VI - virtual dual channel spectrum filter.Overview paper Specifically describes the two-channel spectrum analysis filter design and implementation methods from the interface and functional design, software architecture and key technology area. Meanwhile the paper also introduces the LabVIEW achieve brief principles of instrument software.
