Abstract
In this paper the analysis of roundoff noise in floating point state-space realizations of 2-D digital filters is considered. The variance of the roundoff noise at the output of a 2-D digital filter is derived. It is shown that this variance is proportional to the input signal variance and depends on the order of the system, the entries of the state matrices and the diagonal elements of the covariance and noise matrices
