Abstract
The dummy multiplier model and the conventional estimates for roundoff noise variance in floating-point implementations are compared. Common upper and lower bounds for the noise estimates are derived and experi mental results are presented. Although the two noise estimates have co mmon finite bounds, it is shown that they may differ by more than 10 d B for narrowband lowpass filters.
