    Robust stability of 2-D digital filters employing saturation
    (Ieee-inst Electrical Electronics Engineers inc, 2005) Singh, V
    A computationally tractable, i.e., linear matrix inequality (LMI)-based criterion for the global asymptotic stability of uncertain two-dimensional digital filters described by the Fornasini-Marchesini second local state-space model with saturation overflow arithmetic is presented. The criterion is compared with an earlier LMI-based criterion.

    Elimination of Overflow Oscillations in Digital Filters Employing Saturation Arithmetic
    (Academic Press inc Elsevier Science, 2005) Kar, H; Singh, V
    A criterion for the nonexistence of overflow oscillations in a class of digital filters employing saturation arithmetic is presented. The criterion is based on a novel characterization of the saturation nonlinearity (namely, the 'reduced sector' characterization) and, hence, is quite distinct from previously reported criteria.

    Elimination of Overflow Oscillations in Fixed-Point State-Space Digital Filters Using Saturation Arithmetic: an Lmi Approach
    (Academic Press inc Elsevier Science, 2006) Singh, V
    A criterion for the nonexistence of overflow oscillations in fixed-point state-space digital filters employing saturation arithmetic is presented. The criterion possesses the structure of linear matrix inequality and hence is computationally tractable. The criterion is compared with an earlier LMI-based criterion. (c) 2005 Elsevier Inc.
