Abstract :
The typical inverse problem is the recovery of the input, x, given data, y and the knowledge of the system A. Such problems occur frequently in instrumental science. For the Linear Time Invariant (LTT) systems the governing equation can be expressed in matrix form, y=Ax. In this paper the problem of ill-conditioning of non-minimum phase systems and the relation of the phase structure of the system to the singular values of its system matrix is discussed.
