基于LabVIEW的电磁超声信号采集与分析软件-LabVIEW-based electromagnetic ultrasonic signal acquisition and analysis software

实现双路信号的采集、分析，可对波形进行频谱分析，并可打印博学那个-Achieve dual signal acquisition, analysis, spectral analysis waveform, and can print learned that

本文研究的是利用奇异性指数实现对设备状态监视和故障预警功能。首先用LabVIEW 采集传感器电信号，然后对采集到的电信 号进行小波变换得到信号包络奇异点的奇异性指数，即设备运行状态的特征值-In this research project, we use LabVIEW to do wavelet-transformation to the signal collected by sensors in order to get singularity index from the sin
