Finite word length effects
WebOct 14, 2024 · 2.2 Finite Word-Length Effects. Quantized systems suffer from two types of errors: overflow and precision errors. On the one hand, overflow errors result from variable values growing beyond the limits of the word-length (WL). WebThe accuracy of a digital filter is limited by the finite word length used in its implementation. Techniques have been developed to analyze this problem. Good agreement between the theoretical and experimental results has been reported. This paper discusses some of these accuracy problems and reviews some of the approaches used in investigating them. The …

WebIn the absence of a finite word length effects, synthesis of equation 1.1 is trivial. However, such a realization can produce inaccuracy which is orders of magnitude greater than other realizations. Therefore the cardinal rule, described by Kaiser [l], is to use a design method that permits decomposition of the higher order filter into ...
