实验四

基于LABVIEW的虚拟频谱分析仪，可以对任意信号以及采集卡采集到的信号进行频域分析，同时还加入了时域分析，使功能更为强大。(LABVIEW-based virtual spectrum analyzer can be arbitrary signals and the signal acquisition card for frequency domain analysis, and also joined the time-domain analysis, so that more powerful.)

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,)

华氏度转换为摄氏度，代码短小，可靠性高，转化方便，适合做课后练习(Convert Fahrenheit to Celsius, the code short, high reliability, easy transformation, suitable for after-school practice)

labview 实现声音信号的采集并回放 利用生产者消费者模式(labview s sound acquisition and play back using producer-consumer mode)

labview对access数据库内的数据进行删除 重建等操作(Labview to delete data in access reconstruction, and so on)

基于labview信号采集的源程序，对于初学者有一定帮助(Please enter text to be translated is based on the labview source program signal acquisition, it is helpful for the beginner to content )

labview的一个usb和visa通讯的很好的一个参考例子(LabVIEW a USB and visa communication is a good example of reference)

说明：  本代码编制测距传感器的串口通讯接口VI；通过波形图表显示连续读取的测距-时间曲线，并将有效测量范围外的数据滤除。(This code compiles the serial communication interface VI of ranging sensor, displays the continuous read ranging-time curve through waveform chart, and filters out the data outside the effective measurement range.)

简单地报表生成程序，包含了文字 表格 曲线图，是很好的学习资料(Simple report generation program includes a text table curve, is a very good learning materials)

基于LabVIEW设计的绘制任意系统的Nyquist曲线和Bode图，适合学习控制理论的同学巩固和复习理论知识。(Nyquist and Bode diagram based on LabVIEW curve design draw any system for learning control theory to consolidate and review the students theoretical knowledge.)
