Abstract

A novel algorithm of designing polynomial interpolation filter as anti-imaging filter is presented. The proposed algorithm is based on linear programming techniques and it is easy to implement. Results indicate that the proposed algorithm can achieve maximum attenuation in imaging-band. Furthermore, it is flexible to adjust the frequency response of polynomial interpolator according to different specifications.
