ORCAD implementation of a frequency response function using equivalent circuits

The paper describes the implementation in ORCAD of equivalent circuits, used to model an artificially created frequency response function. The function is implemented and graphically represented in Matlab. Next, we compute the input admittance/impedance of the two proposed equivalent circuits (that include controlled sources), and compare it to the initial function. Finally, we conclude that this method of synthesis of electrical models for frequency responses, approximated by rational functions, is correct.
