This brief proposes a new approach to utilizing positive-offset representation for sign-extension avoidance in shift-and-add implementation of a finite-impulse response filter. Affine arithmetic is used to model the excess offsets in order to curtail the word-length (WL) expansion problem. Tighter p...
