    Abstract: "In this paper, a novel approach is proposed
    to analyze and minimize fixed-point arithmetic errors for
    digital filter implementations based on eigenvalue sensitivity
    measures. First, uncertainties of the filter-parameter caused by
    roundoff and computational errors are expressed in function
    of register length for fixed-point implementations. Sequentially, based on fixed-point statistical model and normal-form
    transformation, a stability criterion of the dynamical filter
    model is derived to form a similarity transformation with
    a sufficient and necessary condition of the stability. Thus,
    eigenvalue sensitivity measure with respect to filter parameters
    is constructed in the sense of induced 2-norm. This measure is
    minimized by an optimal similarity transformation (normalform transformation) obtained from an analytically algebraic
    method. Based upon this transformation as well as the stability
    criterion, a least register length can be obtained. Finally, an
    example is performed to illustrate the effectiveness of the
    proposed scheme."
