Abstract
Coefficients W, Wand Wto be used in finding a new quadratic function f(W) indicating dependence of a distortion component on an coefficient by the least square method are obtained as values that satisfy a relational expression f(W)=f(W)=f(W)+P (where P is a true value) on the basis of a quadratic function f(W) indicating unupdated distortion component coefficient dependence.
