Abstract
A virtual audio analyzer based on USB interface is introduced in this paper to analyze railway audio signals. FPGA is used as the main controller to control A/D converter for data acquisition, USB interface is adopted for data transmission and LabVIEW virtual instrument paltform is used to analyze audio signals. The system has the advantages of low cost and simple reconfiguration. The test result shows that the virtual audio analyzer is stable and powerful.关键词
