Abstract
It is shown that, if series compensation by pole-zero cancellation is used in a system that is linear for small signals but has a large signal nonlinearity in the loop, then an observable mode, corresponding to the cancelled pole, appears in the system response when large transient signals occur in the loop. An example in which the nonlinear element is a saturating device is used to illustrate the point being made.<>
