摘要
在现有用于抑制冲激噪声的非线性数字化滤波算法 (如LOR算法 )的基础上 ,指出现有算法对被噪声污染的样点值的恢复能力不足 ,不能进一步提高精度。进而提出了改进措施 ,给出了利用Lagrange插值公式演变出的能精确估算被噪声污染的样点值的LOR改进算法 (ILOR)
It is indicated that present nonlinear numerical filters (LOR filter being a typical one) used for suppressing impulsive noise in numerical measurement & control system are not enough to resume the sample value corrupted by impulsive noise. An improving measure is discussed. The improved LOR filter (ILOR) is proposed which can accurately estimate the sample value corrupted by impulsive noise.
