Fixed and floating point realizations for low roundoff noise digital filters
José Luis Sanz-González, J.C. Herranz-Tores, Francisco López-Ferreras · 2003
Criteria for comparing fixed-point and floating-point arithmetics are established. It is proved by theoretical analysis and simulation results that low-roundoff-noise structures for fixed-point arithmetic are also low roundoff noise for floating point. Computer results for roundoff-noise power are given, and some conclusions are derived for both arithmetics.>
