IDENTIFIABILITY OF ERRORS IN VARIABLES DYNAMIC SYSTEMS

There has been substantial work done on the Errors In Variables (EIV) identifiability problem for dynamic systems. However, these results are spread across a significant volume of literature. Here, we restrict ourselves to the use of second order properties for single input single output systems. In this case, we present a single theorem which compactly summarizes known results. The theorem also covers several cases which we believe to be novel.
