Abstract
For linear systems, it is known that there exists a state observer if and only if the system is detectable, or in other words, asymptotically stabilizable by output injection. In this paper, it is shown that for a nonlinear system, the stabilizability by output injection is neither necessary nor sufficient for the existence of an observer.
