3 Terms and definitions
JJF1001, GB/T 18777-2009, GB /Z 26958.1-2011 and the following terms and definitions apply to this document.
3.1
Linear profile filter linearprofilefilter
Contour is divided into long-wave and short-wave components of the contour filter.
3.2
Phase correction (linear) profile filter phasecorrect (linear) profilefilter
A contour filter that does not produce a phase shift that leads to an asymmetrical contour deformation is not generated.
Note. Phase correction filters are a special type of linear phase filter because any linear phase filter can be converted to (simply by panning
Weight function) zero phase shift filter, phase correction filter.
3.3
Weighting function
The function used to calculate the centerline, which shows the weight of the neighboring contour points of a point.
Note. The transfer characteristic of the midline is the Fourier transform of the weight function.
3.4
Transmission characteristics of filter transmissioncharacteristicofafilter
Denotes the filter's attenuation of the amplitude of the sinusoidal profile signal, expressed as a function of attenuation versus profile wavelength.
Note The transfer characteristic is the Fourier transform of the weight function.
3.5
Cut-off wavelength
After passing through the contour filter, the amplitude is attenuated by 50% of the wavelength of the sinusoidal profile.
Note 1. Linear contour filters are distinguished by the filter type and cut-off wavelength value.
Note 2. Cutoff wavelength is the recommended nesting index for linear contour filters.
