Abstract :
The evaluation of sensitivity, roundoff noise and dynamic range of digital filters involves the calculation of a number of substructure transfer functions. A method of calculating these substructure transfer functions based upon the multiplier extraction approach is proposed. This new method requires only the evaluation of a series of determinants and thus avoids the need for matrix inversion.
