A result is presented showing the existence of inputs universal for observability, uniformly with respect to the class of all continuous-time analytic systems. This represents an ultimate generalization of a 1977 theorem, for bilinear systems, due to Alberto Isidori and Osvaldo Grasselli.

Under the influence of feedback control and signal processing, it has become customary to regard interconnections as output-to-input assignment. It is argued that this picture is not appropriate for physical systems, where
