To find the sampling distribution of the Chi Square statistic, simply take the outcome of each experiment and compute a Chi Square statistic for that result.
为了找到X平方分布统计的抽样分布，只需获取每次实验的结果，并且计算该结果的x平方分布统计。

This Chi Square statistic will vary from experiment to experiment due to random sampling variability.
由于随机抽样的可变性，因此这个 X 平方分布统计会随实验的不同而不同。

Through the filter experiment on the actual sampling signal, and compares with the common average filter algorithm, it proved the wavelet analysis algorithm has better filter effect.
