44、ng function, s(x), e.g. the Gaussian bell curve according to ISO 16610-21. Because the measured profile, z(x), is always finite, s(x) shall have a local support, l1 x l2, which is normally much smaller than the traversing length. Therefore, the filter formula for the low-pass filter based on the con

The methods are also valid for discrete weighting functions.NOTE 2 The procedure can be applied directly to the profile or can modify the filtration operation.EXAMPLE In the case of the standardized Gaussia

47、n filter (see ISO 16610-21), the weighting function has a local support, e.g. l1= l2= c/2. As shown in Figure 1, the filter formula cannot be applied over the whole traversing length. In the end effect region, either the left side or the right side of the Gaussian bell curve lies outside the profile.EN ISO 16610-28:2016 (E) DIN EN ISO 16610-28:2017-04 7 KeyB1 l2right end effect regionB2 l1left end effect regionaEnd effect region.Figure 1 End effects using standardized Gaussian fil
