Signal power spectrum based on FFT

.用产生三种不同波形，分别计算并显示它们的单边频谱及功率谱，显示低通、带通、带阻、高通四种不同的滤波效果，体会滤波器的使用。(Three different waveforms are produced, and their single side spectrum and power spectrum are calculated and displayed respectively, which show four different filtering effects, such as low pass, bandpass, band resistance and high pass, and realize the use of the filter.)

labview 双通道信号采集和回放系统，可以实现信号采集，设置频率(labview dual-channel signal acquisition and playback system that can achieve signal acquisition, set the frequency)

选择文件路径读取TDMS文件，选择是否校准，选择数据组名及通道名，对数据进行频谱分析(Spectrum analysis of the data from TDMS file.)

用LabVIEW模拟停车场系统,实现分段计时收费(LabVIEW simulation of parking system, to achieve sub hourly fees)

利用LabVIEW编写希尔伯特黄变换HHT的算法，实测可用，包括总程序 ，以及IMF，样条插值等各个子VI 函数(Use LabVIEW to write Hilbert Huang Transform HHT algorithm found available, including the overall program, as well as IMF, each sub-spline interpolation function VI)

在嵌入式触摸屏上用LabView开发的转台人机界面操作平台(To use the LabView development turntable human-machine interface operating platform in embedded touch screen on)

多种调制解调的labview实现,FSK,ASK,PM,FM(A variety of modem labview implementation,FSK QPSK AM FM)

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.)

Labview调用dll文件，实现加、减、乘、除等运算，可以用来学习labview调用dll的方法。(Labview call dll file, add, subtract, multiply, divide, such as computing, the method can be used to learn labview call dll' s.)
