此源程序为用Labview程序编制的，针对采集信号的功率进行分析。-The source code for the use of Labview programming, and for collecting the signal power for analysis.

运用 参数估计法AR 法进行功率谱做图 直接输入待做图信号便可-AR method of parameter estimation method power spectrum do plan direct input to be able to make plans signal

提取原始信号的功率谱就可以看出在哪个频带的能量比较高，噪声主要集中在哪里，这样就可以专门分析那个频带的噪声-The power extracted the spectrum of the original signal can be seen in which frequency band energy is high, the noise is mainly concentrated in where, so that it can be devoted to the analysis of
