An error analysis for 2-D block implemented digital filters
M.R. Azimi-Sadjadi, Robert A. King · IEEE Transactions on Acoustics Speech and Signal Processing · 1983
This correspondence considers error analysis of block-implemented 2-D digital filters. Expressions for error bound and mean-square error for roundoff error accumulation are derived using fixed-point arithmetic, and compared with the results obtained using ordinary 2-D difference equations.
