  • Abstract
    In order to keep the word size of a digital filter fixed, a round-off procedure is usually adopted. This can result in errors in the filter output. In this paper several round-off techniques, including a novel method called ROM-rounding are applied in the implementation of a second-order low pass filter. Results indicate that ROM rounding is a viable and cost effective technique for use in filter implementations.
