Abstract :
A scheme for designing IIR digital filters, with specified coefficient wordlengths based on successive digitization and reoptimization, is presented and compared to related approaches via a number of design examples. The ordered digitization of the coefficients based on their sensitivity, with each digitization followed by reoptimization of the remaining coefficients, results in a much reduced computation effort in comparison to related design approaches.
