Aplication of SI, superinductors and FDNR in frequency filters
Mach, Ladislav ; Brančík, Lubomír (referee) ; Petržela, Jiří (advisor)
This thesis explains possibilities to substitute inductors in electronic circuits and at the same times it shows the calculation of individual discrete elements. An inductor may be substituted in two ways. Either by means of a circuit which directly replaces the inductor as a discrete element, or the circuit may be transformed into another one with similar features. For the second option, however, a synthetic FDNR element has to be used. It is a frequency depended negative resistor. Students can try out the use of superinductors, synthetic inductors in frequency filters with a specially designed facility. They also can transform inductivity and capacity arbitrarily in both directions, higher and lower.

Synthetic elements and their applications in practical education
Stolařová, Hana ; Langhammer, Lukáš (referee) ; Šotner, Roman (advisor)
This bachelor thesis deals with solutions of impedance converters suitable for construction of tunable (or adjustable - select) synthetic elements (two-terminals). Simple applications of these synthetic elements in practical education are supposed. The Antoniou impedance converter represents the core device for various solutions of variable synthetic elements applied in ARC filters (based on RLC original) and simple harmonic oscillator. This thesis includes theoretical design of parameters of circuits for required features as well as verification by computer analysis (PSpice) including fabrication dispersion of elements. This thesis also includes design and fabrication of printed circuit board prepared for execution of a testing device with a form wich can be used for educational purposes in courses Design of Electronic filters and Electronic Circuit Theory.
