Abstract :
The authors present a method to approximate a symbolic network function of any order to a second order one. The method is based on the symbolic calculation of the displacement of the main roots of a polynomial due to the variations of a given parameter, assuming the ideal circuit (polynomial) of order two. Different levels of approximation are possible to tune the desired accuracy. An example is included to illustrate the efficiency of the method
