    Global Robust Stability of Interval Delayed Neural Networks: Modified Approach
    (Wiley, 2009) Singh, Vimal
    A criterion for the global robust stability of Hopfield-type delayed neural networks with the intervalized network parameters is presented. The criterion, which is derived by utilizing the idea of splitting the given interval into two intervals, is in the form of linear matrix inequality and, hence, computationally tractable. The criterion yields a less conservative condition compared with many recently reported criteria, as is demonstrated with an example. Copyright (C) 2008 John Wiley & Sons, Ltd.

    A Note on Determination of Oscillation Startup Condition
    (Springer, 2006) Singh, Vimal
    There prevails a widespread notion that, given a closed-loop system, oscillation will commence and build up therein if the magnitude of loop gain is greater than unity at the frequency at which the angle of loop gain is zero degree. Three novel examples in which this notion fails are presented.

    Stability Analysis of 2-D Digital Filters With Saturation Arithmetic: an Lmi Approach
    (Ieee-inst Electrical Electronics Engineers inc, 2005) Kar, H; Singh, V
    An improved LMI-based criterion for the nonexistence of overflow oscillations in two-dimensional (2-D) digital filters described by the Roesser model employing saturation arithmetic is presented. The criterion makes use of the structural properties (as prevailing in the system under consideration) of the saturation nonlinearities in a greater detail than the usual sector restriction [0, 1].

    Stability of 2-D Systems Described by the Fornasini-Marchesini First Model
    (Ieee-inst Electrical Electronics Engineers inc, 2003) Kar, H; Singh, V
    A sufficient condition for the stability of linear two-dimensional (2-D) systems described by the Fornasini-Marchesini (FM) first model is presented. The condition is compared with previously reported conditions.

    Failure of Barkhausen Oscillation Building Up Criterion: Further Evidence
    (Springer, 2007) Singh, Vimal
    It has been suggested in many textbooks that, given a closed-loop system, oscillation will commence and build up therein if the magnitude of loop gain is greater than unity at the frequency at which the angle of loop gain is zero degree. A novel ideal op-amp based counterexample to this suggestion is presented. The Letter serves to substantiate the findings in a recent Letter. A discussion relating to the finite gain of op-amp is included.
