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 experimental results are presented. Although the two noise estimates have common finite bounds, it is shown that they may differ by more than 10 dB for narrowband lowpass filters. © 1994 IEEE
