| Abstract: | Noises exist extensively in all kinds of circuits.In this research operator decomposition method is used to solve the Fokker-Planck equation of the RLC circuit which is affected by the white noise.A conclusion is drawn that it is consistent with the classic theory,and futher gives a proof for the validaty of the Brownian theory. |
