Abstract :
A structure to realize a first-order two-dimensional all-pass transfer function with five multipliers and two delays has been proposed. This has been achieved by modifying the signal flowgraph of an existing structure which uses six multipliers and two delays. The multipliers of the proposed structure are shown to be real for stable filters.
