Abstract
Filter frequency errors due to coefficient quantization in direct-form realization of zero-phase two-dimensional finite impulse-response (2-D FIR) digital filters are analyzed. Applying a previously published method for 1-D FIR digital filters, the case of 2-D FIR filters with octagonal or quadrantal symmetry is considered. Based on the analysis, statistical bounds on the frequency-response errors and on the wordlength of the filter coefficients are developed and verified by experimental data.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
