Abstract

The paper, mainly intended for the didactic activity, presents the synthesis design of the RC type one-ports. Determination of the impedance function, followed first by its development in elementary fractions related to the poles, allows the obtaining of the Foster I and Foster II circuits, and then its development in continuous fractions allows to obtain the Cauer I and Cauer II circuits. Because synthesis is performed using the same impedance function, the obtained circuits are equivalent. This assertion is also supported by obtaining the same frequency characteristics across the entire frequency range in which circuits analysis is performed using the Orcad software.
