Abstract
This letter presents a method to approximate a symbolic network function of any order to a second-order one. The method is based on the symbolic calcu lation of the displacement of the main roots of a polynomial due to the var iations of a given parameter, assuming the ideal circuit (polynomial) of or der two. Different levels of approximation are possible to tune the desired accuracy. An example is included to illustrate the efficiency of the metho d. Copyright (C) 2000 John Wiley & Sons, Ltd.
