Abstract :
A parallel structure is proposed for implementation of a general quadrant-plane causal 2-D transfer function where each channel is realized such that spatial delays in the two directions are minimal. The appropriate framework is provided by the singular value decomposition technique in conjunction with recent results from 2-D realization theory. The class of quadrantally symmetric filters is especially discussed since it would gain most from the proposed realization structure
