2.This paper presents a study on the relationship between temperature and signal level and the concept of temperature correction curves in CATV systems. Computational formulas for temperatur correction curves are deduced under various conditions
4.Friend, where are you now~? working~? I will not disturb you if you are working now~!!! AMITABHA~!
5.Rational refers to the underlying mathematical representation. This property allows NURBS to represent exact conics (such as parabolic curves, circles, and ellipses) in addition to free-form curves.
6.Non-Uniform refers to the parameterization of the curve. Non-Uniform curves allow, among other things, the presence of multi-knots, which are needed to represent Bezier curves.
