Design of One-Dimensional Linear Phase Digital IIR Filters Using Orthogonal Polynomials

الملخص EN

In the present paper, we discuss a method to design a linear phase 1-dimensional Infinite Impulse Response (IIR) filter using orthogonal polynomials.

The filter is designed using a set of object functions.

These object functions are realized using a set of orthogonal polynomials.

The method includes placement of zeros and poles in such a way that the amplitude characteristics are not changed while we change the phase characteristics of the resulting IIR filter.
