Original Abstract

This paper analyses the influence of fractional-order (FO) impedance element properties on characteristics of frequency filter where the element is employed. Tow-Thomas topology with one capacitor replaced by FO impedance is examined. This impedance is emulated by fifth-order Foster I network which has limited validity of FO impedance properties resulting in distortion of the filter characteristics. Shifting the frequency band of FO element emulation is tested and recommendations regarding the correct filter functionality are provided. The filter properties are also investigated from the viewpoint of characterizing the parameters of the FO impedance element connected to the filter.
