McClellan transformations for two-dimensional digital filtering-Part II: Implementation

A family of 2-D structures is presented for implementing 2-D FIR digital filters designed by means of a transformation of a 1-D design. These implementations are computationally efficient for filters up to degree 50 x 50 and are straightforward to program or build in hardware. Many details of the implementations are discussed such as its susceptibility to coefficient quantization and arithmetic roundoff. A comparison is made between these implementations and other implementations for 2-D FIR filters.
