测量6205深沟球轴承的故障振动加速度信号, 对信号进行时频分析, 利用经验模态分解方法将振动信号分解成不同特征时间尺度的固有模态函数,对每个固有模态函数进行Hilbert 变换得到Hilbert 谱,通过谱分析识别轴承的故障部位和类型, 证实Hilbert 谱的有效性(Measuring 6205 deep groove ball bearing fault vibration acceleration signal, the signal frequency analysis, empirical mode decomposition method to decompose the vibration signal into different characteristic time scales of intrinsic mode functions, the Hilbert transform of each intrinsic mode functions Hilbert spectrum, spectral analysis to identify the location and type of bearing failure, confirmed the effectiveness of the Hilbert spectrum)

考虑你在哪里不同的传感器，桥上两侧的汽车造成的振动记录收集数据的情况。当你分析这些信号，则可能需要对齐。假设你有3个传感器以相同的采样速率工作，他们是造成同一事件的测量信号。(Consider a situation where you are collecting data different sensors, recording vibrations caused by cars on both sides of a bridge. When you analyze the signals, you may need to align them. Assume you have 3 sensors working at same sampling rates and they are measuring signals caused by the same event.)

400赫兹矢量控制直流逆变电源MATLAB仿真(The 400 Hertz vector control DC power inverter MATLAB simulation)

it is a code in MATLAB for calculation of bit error ratio vs signal to noise ratio , for multiuser code division multiple access .. usually in any communication system calculation of BER is very important to know the performance of system .. so in this program multiuser CDMA system is used ,, spreading is done using HADAMARD matrix .. or WALSH code .. and BER vs SIGNAL to NOISE ratio graph is computed
