子波分析是一种日益获得广泛应用的信号处理新技
术, 具有良好的时-频局部化特性, 尤其适用于时变及非平
稳信号。本文简述了子波函数与子波展开的基本概念, 利用
展缩子波和调和子波将信号及信号均方值进行时-频两维
分布。最后采用了三种子波分析方法对轴承故障进行诊断,
即使对现有各种方法尚难以诊断的滚动体故障, 也能获得
满意的结果, 说明子波分析的确为机械故障诊断提供了强
有力的分析手段。(Wavelet a nalysis, as a new technique of signal processing , possesses ex cellent characteristic
of time-frequency localization and is suitable for analyzing
the time-var ying or transient signals. In this paper , the basic concepts of wavelet function and
wavelet expansion are briefly introduced. The time frequency
distribution of signal and its energy are obtained by decomposition via dilating wavelet and harmanic wavelet. )

work
1) 以身高为例，画出男女生身高的直方图并做对比；
2) 采用最大似然估计方法，求男女生身高以及体重分布的参数；
3) 采用贝叶斯估计方法，求男女生身高以及体重分布的参数（假定方差已知，作业请注明自己选定的一些参数情况）；
4) 采用最小错误率贝叶斯决策，画出类别判定的决策面。并判断某样本的身高体重分别为(160,45)时应该属于男生还是女生？为(178,70)时呢？(1) taking height as an example, draw the histogram of male and female students and compare them;
2) the maximum likelihood estimation method was used to calculate the height and weight distribution parameters of male and female students;
3) using Bayesian estimation method to find the parameters of height and weight distribution of male and female students (assuming the variance is known, please indicate some of the parameters selected by the job);
4) using the minimum error rate Bayes decision, draw the decision surface of category decision. And determine the height and weight of a sample respectively (160,45), should belong to the boys or girls? What about (178,70)?)
