摘要
从理论上分析和论证了冲击波数字测量时所用的平滑滤波的方法和效果,给出了滤波后误差的均值和方差,最后以一阶平滑滤波为例分析了平滑点数对平滑效果的影响。
The method and effect of smoothing filtering used in digital measurement of impulse wave are analysed theoretically in this paper. The paper derives the mean value and standard divation of errors after filtering. Effects of one order smoothing filtering are discussed here. The relation between number of smoothing points and smoothing effects is included.
