Abstract : Continuous-time systems with discrete measurements are considered. It is shown that the technique of [7] can be used to design converging observers in the case where the size of some intervals between 2 measurements is larger than the upper bound ensuring convergence of the observer that is provided in [7]. A scarcety condition on these intervals is exhibited. This result is established through a recent stability analysis technique called trajectory based approach.
