| 摘 要： | 滤波是数据采集和处理的一种常用技术手段，本文就汽车碰撞试验中有关滤波的问题进行探讨，用冲激响应不变法实现了满足通道频率特性要求的实用算法，为了消除相位误差采用正反向二次滤波的方法，但它会引起幅频特性改变，并对此提出了修正的方法。

| Abstract: | Filtering a basic operation of data acquisition and data processing in vehicle crash test is discussed in this paper. The impulse response invariant method is used as a practical algorithm meeting the requirement of Channel Frequency Class. For eliminating the phase error, both the positive and negative filtering are adopted with a correction for the change of amplitude and frequency characteristics. |
