Abstract Based on the linear system theory, applying the statistical properties of the trichotomous noise, the analytical expression of the output amplitude gain (OAG) is derived.It is shown that, with the increase of the frequency of the input signal, the increase of the stable probability of the trichotomous noise, the increase of the switching rate between the noise states, as well as the increase of the parameter k (the reciprocal of capacitor C), the system OAG reaches a maximum value.For low signal frequency, with the increase of k, the OAG decreases monotonically, while for high signal frequency, the OAG increases monotonically with the increase of k.For low signal frequency, with the increase of the stable probability, the OAG increases monotonically, while for high signal frequency, the OAG decreases monotonically with the increase of the stable probability.The OAG decreases monotonically with the increase of the parameter G0 (the reciprocal of resistance).
