PROJECT TITLE :

The Phase Characteristics for the Stability of 2-D Nonsymmetric Half-Plane Digital Allpass Filters

ABSTRACT:

The section-response property for the bounded-input bounded-output (BIBO) stability of a two-dimensional (2-D) causal recursive digital allpass filter (DAF) with nonsymmetric [*fr1]-plane (NSHP) support region is presented. Each cases of filters with real coefficients and complicated coefficients are explored. Moreover, the effect of the numerator polynomial of a two-D NSHP DAF on stability is additionally considered. The presented phase-response property has several applications. A outstanding application is that it will be utilized to enforce stability for a two-D NSHP DAF style by choosing an applicable part specification. The eigenfilter style of 2-D NSHP DAFs for this application is additionally presented. Style examples are given to indicate these applications and the soundness of a 2-D NSHP DAF is additionally inspected by the two-D spectral factorization-based mostly algorithm and a zeros-examining technique presented by Ekstrom and Woods for confirmation.
