Information System Assessment and Proposal for ICT Modification
Stejný, Jiří ; Zetík, Rostislav (referee) ; Koch, Miloš (advisor)
The diploma thesis deals with information system in Telefónica O2 Czech Republic company. The thesis is focused on describing the existing enterprise information system especially in terms of processing customer requirements and their impact on customers. The aim is to draft changes in the information system of conflict resolution department orders. The changes are geared to enhancing the effectiveness of staff members and increase customer satisfaction.

Design of tunable frequency filters with modern current active elements
Stejný, Jiří ; Herencsár, Norbert (referee) ; Jeřábek, Jan (advisor)
This master´s thesis deals an active elements called digitally controlled current amplifier, multiple-output current follower and its usage in tunable frequency filters. These tunable frequency filters operate in a pure current mode. In the first part of this work are presented the different types of current active elements. Universal current conveyor, multiple-output current follower, digitally controlled current amplifier (UCC, MO-CF, DCCA). In the second part of this work are introduced particular methods of design tunable frequency filters. Special attention is given to using the design method of via autonomous circuits because it is one of the most. In the last part of this thesis are designed and computer-simulated individual multifunction tunable frequency filters with those already active yet elements. These filters were designed via autonomous circuits or modification of existing circuits. The functionality of the proposed filtres have been verified by computer simulation. Snap3 program was used for the symbolic analyse of circuit and OrCad PSpice program was used to simulate the characteristics of multifunction filters.
