Abstract :
A number of stable and lossless first-order two-dimensional all-pass and all-pole digital filter structures each with two delays, two multipliers, and six adders are presented. Owing to the losslessness property, zero-input oscillations can easily be eliminated by magnitude truncations. The resultant structures are modular and are suitable for VLSI implementation
