This paper advances a method for treating the random vibration signal and noise signal of silkworm chrysalis, and probes into how to eliminate the disturbing values in the random vibration signal of silkworm chrysalis.

By comparing the phase space of the “signal noise” received by an oceanic lidar with those of the deterministic signal, the stochastic signal and the chaotic signal, it is found that there exists similarity between the phase trajectory characteristics of the signal noise and the chaotic signal.

There are two kinds of noises, the one is the inner noise such as thermal noise and conductivity noise, and another is the outer noise which caused by network effect or synaptic transmission such as signal noise.
