Previous approaches on block realization of recursive digital filters have been based on block-state and parallel block-state representations. However, the multiplication complexity of these block structures is proportional to the square of the block size, and hence is unacceptable for very large block sizes. The authors introduce an incremental block-state structure for block realization of linear time-invariant recursive digital filters of multiplication complexity that is linear in block size. Block realization of multirate recursive digital filters by means of the incremental block-state structure is also presented.
