Abstract：Noise frequency modulation(FM)jamming。which belongs to blanket jamming。is already become the main form ofnoise jamming at present。because the wideband was gained by it．Tne spectnlnl ofnoise FM jamming is analyzed by time domain autocorrelation method in this paper．It’S jamm g peculiarity and几out— putting signal’S jamming peculiarity ale explained．At last，these time series models ofnoise FM jalllIIling sig— nal and几outputting signal ale built．(Abstract: Noise frequency modulation (FM) jamming. which belongs to blanket jamming. is already becomethe main form ofnoise jamming at present. because the wideband was gained by it. Tne spectnlnl ofnoise FMjamming is analyzed by time domain autocorrelation method in this paper. It S jamm g peculiarity and several out-putting signal S jamming peculiarity ale explained.

基于EMD的直流电机换向电流提取程序。内含用LEM公司的霍尔传感器实测的微型直流电动机启动时的电流信号（真实的数据和大家分享），分别用小波滤波和EMD消噪，并用EMD提取直流分量、高频换向电流，对研究电机间接测速、启动特性测试很有帮助，对电机故障诊断也有帮助。(EMD-based DC motor commutation current extraction procedures. LEM s included with Hall sensors measured miniature DC motor start-up current signals (real data and to share), respectively, with wavelet filtering and EMD de-noising and extracted DC component with EMD, a high-frequency current commutation of indirect research motor speed, starting characteristics testing is helpful, for motor fault diagnosis can also help.)

this will helpful for region merging algorithm
