On the elimination of zero-input limit cycles digital filters)
Jacques Szczupak, C.R. Green · 2002
Sufficient conditions for avoiding zero-input limit cycles are derived by considering generic structures. The method is based on a fixed-point finite precision arithmetic nonlinear network modeled as a linear time-varying network, allowing the extension of time-invariant conditions. Second order delay and multiplier canonic structures that satisfy the conditions are investigated. An illustrative case is included.>
