Effects of zeros on IIR filters with symmetric impulse response

The properties of the symmetric impulse response filters with real and complex zeros are considered. The pole-zero locations of the rational transfer functions are found, by minimization of the symmetry error. The contribution of zeros to the symmetry error is shown and compared to the systems with all zeros at the origin. The design procedure of such filters based on time or frequency domain requirements is outlined.
