## Abstract The problem of efficiently approximating real frequency data, which represents either measured information of a physical system or idealized curves to be realized by rational positive real (PR) or bounded real (BR) functions is considered. The final rational function is guaranteed in ad

β¦ Synopsis
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 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. Di!erent levels of approximation are possible to tune the desired accuracy. An example is included to illustrate the e$ciency of the method.

## Abstract This article presents a method for the interchange of a secondβorder circuit with high __Q__βfactor poles by a more complicated network that consists of several low __Q__βfactor stages. The ratio of the substituting circuit transfer function to the given secondβorder transfer function a
A numerical method based on the Taylor polynomials is introduced in this article for the approximate solution of the pantograph equations with constant and variable coefficients. Some numerical examples, which consist of the initial conditions, are given to show the properties of the method.
