| Abstract: | High frequency switch power supply used in railroad communications provides railroad communications network with driving force. Noise voltage is an important electric parameters to judge the quality of switch power supplye. The power noise voltage exceeding specified value can affect the operation of communications network.This paper analyzes the content of the noise voltage and its impact on communications equipment, and introduces the testing methods of noise voltage. |
