基于声卡的语音识别，用了LMCC等算法，包括消噪(Sound card based speech recognition, with the LMCC and other algorithms, including the de-noising)

说明：  计算1——n的平方和大于1000的n的最小值，并计算出累加和(Calculate the sum of squares of 1-N and the minimum value of N greater than 1000, and calculate the sum of accumulations.)

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.)

基于labVIEW的最小二乘法算拟合正弦波计算相位(Calculated based on least squares fitting labVIEW calculated phase sine wave)

用LABVIEW实现保存数据的功能，使数据不会没有了(LABVIEW save data, so that data would not be without)

说明：  labview modbus协议下的串口通信(Serial communication under LabVIEW Modbus Protocol)

Labview的3D控件的功能介绍，还有三个例子程序：陀螺仪，2D魔方，3D魔方。(Function Labview 3D controls introduction, there are three examples: gyroscope, 2D Rubik' s Cube, 3D cube.)

基于声卡的虚拟仪器设计实例集锦，里没有信号发生器，示波器，扫频仪(Sound card based virtual instrument design example highlights, there is no signal generator, oscilloscope, Sweep)

说明：  本项目是以 LabVIEW 为开发平台的环境监控与预警系统，实现了对温度，烟雾和电压电流等信号的实时采集、记录、存储和回放等功能程序的模块化设计，从而达到环境监控的目的。(This project is an environmental monitoring and early warning system based on LabVIEW. It realizes the modular design of functions such as real-time acquisition, recording, storage and playback of signals such as temperature, smoke and voltage and current, thus achieving the purpose of environmental monitoring.)

通过串口读取数据，利用示波器实现波形的显示，同时具有保存数据，回放图形的功能。(Read data through the serial port, use an oscilloscope to achieve waveform display, but also has to save the data, playback graphics.)
