| Abstract: | Interference and the damping methods for a slowly varying parameter measuring system used in rocket engine tests were introduced in this paper. Proper arrangement and grounding of the cables are important factors be firstly considered. Signal regulator and software technology are used successfully in interference damping. Application of digital wave filtering technology, signal detecting technology and "watchdog" technology are proved to be effective methods. |
| Keywords: | measurement interference damping noise |
