| Abstract: | This paper expounds the phenomenons of side band of default signals which is oc- cured in machine running,for examlpe,such as rotating bearing,and preliminarly analy- ses the reason of occuring side band phenomenons,and introduces a way on how to dis- tinguish the signal of side band—the technical duospectrum. |
