说明：  用有效独立法实现传感器优化布置，效果一般，但可供借鉴(Using the effective independence method to realize the optimal arrangement of sensors)

介绍了随机信号处理，并重点阐述了卡尔曼滤波在随机信号处理中的应用，并有matlab仿真的实例。(Introduction to Random Signals and Applied Kalman Filtering with Matlab Exercise)

This function is a very simple application of FFT2 for an image to simulate the effect of bandpass filter with two cut off frequencies. One can easily modify the programme to do the processes for different images, and even implement highpass and lowpass filter
