Um novo método iterativo para a compensação do efeito sen X/X em conversões D/A.

Abstract

This work presents a new method for the compensation of the sin x/x distortion which is inherent to signal conversions from digital or sampled-data waveforms to continuous-time waveforms. The new method iteratively adjusts the poles Q factors of the original transfer function of the system in order to minimize the passband error due to the signal conversion. The algorithm proposed is naturally convergent and requires very little computational effort. Examples are presented to illustrate the applicability and the efficiency of the proposed technique.
