Each member body interested in a subject for which a technical committee has been established has the rig

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures

It influences the feature characteristics and

39、 measurement chain links 3 and 5 in the GPS matrix structure.The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this part of ISO 16610 is a part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of ISO 16610 and the default decision rul

40、es given in ISO 14253-1 apply to specifications made in accordance with this part of ISO 16610, unless otherwise indicated.For more detailed information about the relation of this part of ISO 16610 to the GPS matrix model, see Annex F.This part of ISO 16610 develops the terminology and concepts of s

41、pline filters.The spline filter has an advantage over a conventional phase correct filter in that for open profiles, the ends of the measured profile are still usable.6 EN ISO 16610-22:2015 (E) DIN EN ISO 16610-22:2016-041 ScopeThis part of ISO 16610 specifies spline filters for the filtration of pr

42、ofiles. It specifies in particular how to separate the long- and short-wave component of a profile.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

48、isfy the filter equations given in 4.3.2, for open profiles, and 4.3.3, for closed profiles.NOTE A comparison with Gaussian filters is given in Annex B, and illustrative examples are given in Annex C. A concept diagram for the concepts of spline filters is given in Annex D, and the relationship to t

49、he filtration matrix model is given in Annex E.4.2 Weighting functionThe weighting function of a spline profile filter cannot be given by a simple closed formula. Filter equations are therefore used instead of weighting functions to describe the spline profile filters. However, where necessary, a numerical calculation of the weighting function for a spline profile filter is always possible. If the sampling interval x is small enough, and the spline profile filter is based on cardinal
