Design of zero phase IIR Nyquist filters
X. Zhang, Toshinori Yoshikawa · Electronics Letters · 1997
A new method for designing zero phase IIR Nyquist filters with zero intersymbol interference is presented. The proposed method is based on the eigenvalue problem by using the Remez exchange algorithm in the stopband, and the optimal filter coefficients can be easily obtained by computing the absolute minimum eigenvector and applying an iteration procedure.
