In this correspondence, error analysis for two-dimensional direct form recursive digital filters employing floating-point arithmetic is carried out. A systematic way of estimating the mean-squared errors due to roundoff, coefficient, and input quantizations is discussed. Norm error bounds are also given. Extensive numerical experiments have shown that the present approach leads to satisfactory results.
