| Abstract: | The paper analyzed some methods of real-time data sampling in Windows 2000/XP platform and proposed an optimal solution using the mechanisms for real-time application in Windows 2000/XP. For disserting the design idea, A vibration signal sampling system was proposed as an example application and experimental data was given which indicates that this solution can fulfill the requirements of real-time application. The practical result has proved to be successful. |
