frequency-spectrum

说明：  labview 振动分析软件,该软件可通过声卡采集信号(LabVIEW vibration analysis software that can be collected through the sound signal)

通过设定扫频范围及采样信息，产生一个chrip 信号。(generate a chirp signal, this vi could be used as a signal generation for free.)

说明：  采用数据保存用户名、密码等数据，同时具备修改、添加、删除用户信息等(User name, password and other data are saved by data, and user information can be modified, added and deleted at the same time)

用LabVIEW编写，从excel中读取数据到labview中，将labview数据存储到excel中 这个比较简单了，直接利用写入电子表格文件VI。(Write in LabVIEW, read data from Excel to LabVIEW, store LabVIEW data into Excel This is a simple way to write directly to the spreadsheet file VI.)

Get file info in LabView (creation, modification date, etc...)

5124采集程序，频谱显示，时域波形显示，存储，通道之间的相位差计算(5124 collection procedures, spectrum display, time-domain waveform display, storage, compute the phase difference between channels)

基于Labview的声音检测技术CAA文献，可鉴别人声，运用了Matlab小波分析。(Labview-based voice detection technology CAA literature, can identify the human voice, the use of Matlab wavelet analysis.)

使用LabVIEW对输入波形经行傅里叶变换，对比时域信号与频域信号。(LabVIEW for use by the line of the Fourier transform of the input waveform, compared to the time domain signal and frequency domain signals.)

自编采用Labview编界面，与研化USB及串口模块通信采集温度、压力，以及数据分析图。程序中设置了数据保存功能，数据文件可以使用Excel打开。(Self compiled using Labview interface, and research-based USB and serial communications modules collect temperature, pressure, and data analysis graph. Program to save the data set, data files can be opened using Excel.)

说明：  实现串口 高速数据采集并通过波形显示。还有发送按键发送数据给下位机。(High speed data acquisition through serial port is realized and displayed by waveform.)
