CLA's cost function is not directly related to a proximity measure between the frequency response characteristics of the filters, but is based on the Mean Square Error (MSE) criterion between the output of the original polynomial and the output of the resulting factorable polynomial for various real values of [absolute value of [z.sub.1]] < 1 and [absolute value of [z.sub.2]] < 1.
Using that approach we were able to obtain exact solutions for factorable polynomials and excellent approximate solutions for nonfactorable polynomials.
