Sonar-SonVI

一个简单的声音采集系统，有声音采集和声音回放功能，还可以将采集到的声音在时域频域进行分析(A simple voice acquisition system has the functions of voice acquisition and playback. It can also analyze the collected voice in time domain and frequency domain.)

labview编写的EMD分解程序 经验模态分解方法（EMD）在非平稳信号的分析和处理中起着重要的作用，为了能够方便的使用EMD方法对信号进行处理，现将LabVIEW虚拟仪器开发平台良好的用户图形界面和MATLAB软件强大的数值分析功能相结合,利用LabVIEW调用MATLAB实现EMD信号处理方法。仿真结果表明对信号进行EMD分解后，使得瞬时频率具有了物理意义，但只是对信号进行了初步处理，可根据实际需要进行相应后续处理。(the labview written EMD decomposition process.Empirical Mode Decomposition (EMD) plays an important role in the non-stationary signal analysis and processing, signal processing in order to be able to facilitate the use of the EMD method, now LabVIEW virtual instrument development platform graphical user interface and the MATLAB softwarepowerful numerical analysis capabilities combined LabVIEW calling MATLAB the EMD signal processing method. Simulation results show that the signal with EMD, making instantaneous frequency has the physical meaning of the initial treatment, but only the signal, the appropriate follow-up treatment can be based on actual needs.)

说明：  NI USB-6001电压/阻测试项目源代码（labview2017） 1，使用io触发，自动扫描io上升沿，输入io可选。 2，使用差分方式采样，双通道同时采样，采样数据实时显示。 3，可手动触发采样，采样率，采样数，测试周期可自定义。 4，可保存控件值，运行程序自动加载上次保存的控件值。 5，数据保存到.xls表格，每天新建以年-月-天命名的文件，每个月创建一个文件夹存放数据。 6，测试结果通过USB-6001自带io输出。 真实项目应用源代码!(1. Use IO trigger to scan the rising edge of IO automatically. Input IO is optional. 2. Sampling by differential mode, sampling by two channels at the same time, and real-time display of sampled data. 3. Sampling can be triggered manually. Sampling rate, sampling number and testing period can be defined. 4. The control value can be saved, and the last saved control value can be automatically loaded by the running program. 5. Data is saved to the. xls table. New files named year-month-day are created every day, and a folder is created every month to store data. 6. The test results are output by USB-6001 with io.
