频谱选取，一般用于后续向量机的诊断的特征。进行了频谱分析后对每个频带的能量进行分离开。(Spectral selection, generally for subsequent diagnostic feature vector machine. Spectrum analysis conducted after the energy of each frequency band to leave.)

when SNR is high , 1st sample estimator provides good estimate of A. it has no noise effect . so we don’t need averaging effect to reduce noise when SNR is high. However variance is still low in sample mean estimator which shows that in reality ,sample mean is good estimator than 1st sample estimator. So, for high SNR, we do not need to reduce the effect of noise by averaging. or we can say that for high SNR let say >1000 , 1st sample estimator got reduced noise. But as for as variance is concerned , the sample mean has low variance for high SNR as well.
