本设计基于对LabVIEW Signal Express3.0进行分析、检测仿真信号。实践证明LabVIEW Signal Express是一种功能强大的软件，能够实现各种硬件可以完成的任务。由于时间等关系我们只研究其扩展部分，即调用分析VI子程序——虚拟双通道频谱滤波器。论文从概述界面及功能设计、软件结构及关键技术等几个方面，具体介绍了双通道频谱分析滤波器的设计思想和实现方法。同时也介绍了LabVIEW实现虚拟仪器的简要原理。

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.
