说明：  基于Labview的声音信号的采集与存储，小玩意儿(Collection and storage of sound signals)

使用labview操作数据库的函数，可以进行插入、删除，查询等操作。(Labview database operations using functions, you can insert, delete, query and other operations.)

labview登录模块，有注册，登录，忘记密码，修改密码的功能，数据库用的是access。(The LabVIEW login module has the functions of registration, login, forgetting password and modifying password. The database uses access.)

LABVIEW程序 实现滤波 快速傅里叶变换并进行频谱分析(LABVIEW program realization filter fast Fourier transform and spectrum analysis)

1．采用Labview设计一虚拟函数信号发生器， 通过数据采集卡输出波形信号，调节信号的相关参数，可观察示波器上波形的变化情况。 ⑴ 以NI MyDAQ数据采集卡作为输出接口； ⑵ 数据采集卡输出多种信号，至少完成三种波形：正弦波、三角波、方波(可调占空比)的输出，同时前面板上显示各输出波形； ⑶ 频率、幅值、初相位、直流偏移量和方波的占空比（0～100 ）等参数可以通过前面板控件调节。 ⑷ 前面板可显示输出波形。(1. Labview design using a virtual function signal generator, data acquisition card output waveform signal, adjust the relevant parameters of the signal can be observed on an oscilloscope waveform changes. ⑴ with NI MyDAQ data acquisition card as output interface ⑵ data acquisition card output a variety of signals, to complete at least three waveforms: sine wave output, triangle wave, square wave (adjustable duty cycle), while each of the output waveform is displayed on the front panel ⑶ frequency, amplitude, initial phase, the DC offset and duty cycle square wave (0 to 100 ) and other parameters via the front panel controls to adjust. ⑷ output waveform can be displayed on the front panel.)

labviews中连接数据库德尔工具包，版本为2.1，内涵破解工具，很难找到的。(this is a CVI_labviews tool used to connect to databases, many common functions are integrated into the function pointer, enjoy it.)

基于LabVIEW软件编写，利用Hilbert变换实现回声信号的检测。(Hilbert transform echo signal detection)

实现功率信号谱的测量，功能丰富，可测性较强，能够实现复杂功能(Achieve power signal spectrum measurement, feature-rich, testability strong, complex functions can be achieved)

Labview宝典课件，非常适合初学者学习的一点即通的学习资料(Labview Collection courseware, very suitable for beginners to learn the point that through the learning materials)

说明：  产生若干个周期的正弦波数据，以当前系统日期和自己的名字为文件名，分别存储 为文本文件、二进制文件和电子表格文件。(Create text file, data record file and write)
