ROUNDOFF NOISE ANALYSIS OF FINITE WORDLENGTH REALIZATIONS WITHTHE IMPLICIT STATE-SPACE FRAMEWORK

摘要

The analytic evaluation of the system output roundoff noise isrnan interesting approach to analyze the effect of a Finite WordrnLength implementation of linear filters. Previous works havernintroduced the Roundoff Noise Gain in this context and appliedrnit to shift and d-realizations.rnTo generalize them, the paper is based on a more general representationrnand exhibits the output noise power in the generalrncase.rnFinally, the problem optimal realization problem, accordingrnto the Roundoff Noise Gain measure, is considered.
