Resumen:

A simple scale-invariant criterion is proposed for picking out state variables that 'significantly participate' in the construction of selected modes of a linear time-invariant dynamical system. The criterion is of value in such approaches to modal reduction as Davison's method, singular perturbation methods, and our 'Selective Modal Analysis' framework (which in several respects extends the former two methods, and in which the proposed criterion arises in a natural way). Application to sampled-data systems is also considered.
