| Abstract: | Based on the analysis on the generation mechanism of electronic noise in electric system of vehicles, a special simulation experimental platform is built. The observation on the electronic noise of a Kinglong coach in both time and frequency domains is conducted. And the noise power spectra are calculated using Welch technique with the electronic noise characteristics of the coach studied. |
