program

以开沟机为背景，程序结合了队列、通知器、状态机等多种结构，实现了参数（两个模拟量、一个脉冲量）的采集、控制的输出（模拟量输出）以及数据的保存。版本已经改为8.6版，大家一同交流学习，共同进步！(In the background trencher, the program combines the queue notifier state machine, a variety of structures, the parametric (two analog, a pulse volume) of the acquisition, the control output (analog output), and data storage . Version has been changed to version 8.6, all of them will share their knowledge and common progress!)

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)

航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency )

Labview双通道采集模拟电压，显示波形图并保存数据未TXT格式。(Labview Dual Channel Data Acquisition and Storage)

包括一些labview实验范例，大部分用到了数据采集卡（USB6009），过桥板，实验板，如信号灯系统。(Including some labview experimental examples, most of them use the data acquisition card (USB6009), bridge board, experimental board, such as the signal system.)

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.)

使用labview进行信号分析，主要用到了傅立叶变换和小波分析，私家珍藏，互联网上其他地方是找不到的(Labview signal analysis, the main use of the Fourier transform and wavelet analysis,)

labview串口的队列接收方式，有效解决labview串口接收时字节错乱问题(labview visa queue send and receive)
