This paper presents a technique for the spectral shaping of roundoff noise in fixed-point implementations of digital filters. An automated feasibility test is introduced, in order to decide whether a given filter realisation meets user-specified constraints on the roundoff noise power spectrum. This feasibility test is used by an algorithm for optimization of individual signal widths within a filter structure. Some results are presented, illustrating how the optimization produces filters… CONTINUE READING
