  • Abstract
    An improved L2-sensitivity measure for linear state-space digital systems is presented. It gives a more precise evaluation of the transfer function deviation ΔH(z) between the infinite wordlength system and the finite wordlength system when the structure matrices {A,b,c} contain 0 and ±1 coefficients. This new measure can be applied in the system optimization resulting in a computationally efficient and very low L2-sensitivity structure. The theoretical result is confirmed by a numerical example
