摘　　要：提出了高性能振动信号检测系统的主要技术指标，进一步针对抗混滤波器幅频特性、相频特性、可实现性及系统采样频率间的相互依赖、相互矛盾与相互制约关系，给出在一定误差意义下的设计方法。A high performance vibration signal detection and processing system was introduced.In view of the importance of the anti aliasing filter of the system,a relationship between the types and orders of the filter and its sampling freguency and errors has been established in the paper.Due to the fact that a signal would be distorted after passing through an anti aliasing filter,a compensation method by using software was developed.
