摘要
Abstract
The typical topological structures of common data acquisition systems are introduced. Transmission,filtering, amplification and A/D conversion of the weak signals are analyzed according to the characteristics of weak signals. By improving topological structure,optimizing design and analysing the error of data acquisition system,a whole solution was provided for da⁃ta acquisition of weak signals. The test result indicates the solution can achieve the high⁃accuracy data acquisition.关键词
