In order to enlarge the difference of fault line and normal line, the complex wavelet pocketband entropy of all sub-frequency bands in feature band is made product.
In order to avoid misjudgement in all kinds of fault condition, a criterion is defined that the maximum of complex wavelet pocketband composite entropy divisions the secondary maximum of that.
为了有效避免各种情况下的选线误判，将所有线路的频带复合熵最大值与次最大值之比作为选线依据。

It features a heavy titanium timepiece mounted in a metal band, but you can ditch the band and put the timepiece in a slick pocket watch housing.
