s = 4000; the width of filter windows ts numbers per windows筛选器窗口的宽度 ts每个窗口的数量 wx = hanningts; generates a hanning filter coefficients产生一个汉宁 滤波器系数 fs = 200

% Explanation of the code:

% The code performs signal processing on two sets of data (data1 and data2) using a hanning filter and a butterworth filter. It then calculates the cross power spectrum, coherence, and phase between the two sets of data for a range of frequencies.

% The width of the filter windows (s) and the sampling rate of probes (fs) are defined at the beginning of the code. A hanning filter is generated using the 'hanning' function and a butterworth filter is generated using the 'butter' function. The data is then processed using the butterworth filter.

% The FFT (Fast Fourier Transform) of the data is then calculated for each filter window using the 'fft' function. The frequency series is calculated using the formula f = n*fs/N, where N is the number of data points and n is a vector from 0 to N-1. The cross power spectrum, coherence, and phase are then calculated for each filter window using the 'sum' function.

% The output of the code is a series of figures showing the power spectrum, cross power spectrum, coherence, and phase for the two sets of data.
