ABSTRACT
We consider usually the linear systems by separating the study of their reactions and properties under zero initial conditions from the study of their reactions and properties under zero input variables. This has been advantageous for attacking many problems among which are the zero-state system equivalency and the zero-input system equivalency [4]. P. J. Antsaklis and A. N. Michel noted that the zero-state system equivalency and the zero-input system equivalency do not necessarily imply the system equivalence ([4, p. 171]).
