Design of two-dimensional recursive digital filters with coefficients of finite word length
Giovanni L. Sicuranza · IEEE Transactions on Acoustics Speech and Signal Processing · 1982
An approach for the design of two-dimensional (2-D) recursive digital filters with coefficients of finite word length is described. The method is derived from a "continuous" optimization procedure which appears to be particularly suitable to meet both amplitude and phase specifications in the frequency domain. The proposed algorithm finds good solutions in a comparatively short computer time.
