摘　　要：以航空发动机试车计算机辅助试验（ＣＡＴ）系统为例，介绍了信号采集与处理中采用的抗干扰措施及滤波技术，以满足ＷＰ系列发动机试车ＣＡＴ系统中稳态、动态和过渡过程参数的采集速度与处理精度的多项技术要求。Based on the development of the computer aided testing technique, combined with the study of the aeroengine test CAT system, and with a computer aided testing system for aeronengine as an example, an anti interference and filtering technique for signal processing is discussed, and applications of the anti interference,digital filtering and analog filtering for the areoengine test are introdued. With the manufacturing practice in engine and its heavy repairing factories, it is proved that the system meets accuracy requirements of parameter acquisition and processing in stationary, dynamic and transient states of the WP series aeroengine test run in the CAT system.
