Laboratory kit for demonstration of active low pass, high pass and band pass filter by Sallen-Key structure
Kadlec, Michal ; Smejkal, Vladimír (referee) ; Slezák, Josef (advisor)
The main aim of this work is to design electric circuit for realizing of low pass, high pass and band pass filter using Sallen – Key structure. It is active filter so this work pays attention to choose the suitable active element. I will analyze individual types of frequency filters, simulate designed structure and will choose suitable computing amplifier for our structure. I will simulate every circuit with ideal operational amplifier, with operational amplifier having real parameters and finally with our chosen operational amplifier. I will confront the difference of individual circuit, influence of real parameters of amplifier for the general process of resultant filter modul characteristics. I closer take a look at the output resistance influence of operational amplifier for the modul characteristics of choosen circuit (low pass filter). This project also includes the summary and analyses of individual possibilities of the electronic control applied to active filter parameters. The part of the project is also detailed analyze and process of realization of the final connection of laboratory instrument.

Optimization of production of thin films of metallic materials
Čejka, Marek ; Kadlec, Michal (referee) ; Šubarda, Jiří (advisor)
The present thesis deals with optimization of the formation of thin layers of metallic materials. In the theoretical part was elaborated overview of the implementation of the formation of thin- film structures, particularly using vacuum techniques. Chemical and physical vapor deposition. They were described methods of pretreatment of thin layers. The findings were discussed methods of controlling the pre-treated surface, quality control and mutual adhesion of coating layers. In the experimental part of the pre-treatment methods were selected and applied to selected substrates. Pretreatments were evaluated using a control surface by wetting angles and by atomic force microscopy. Then, the metal structure formed of copper on the pretreated substrates. Implementation by means of magnetron sputtering. Adhesion layers was checked by testing the surface lattice method. The quality was observed by scanning electron microscopy. The results were used to design the technological process of making metal layers.

Behaviour of varnish composite in various environmental condtions
Kadlec, Michal ; Frk, Martin (referee) ; Rozsívalová, Zdenka (advisor)
The diploma thesis is focused on the preparation of test samples of paint-filled micronized mica and analysis of electrical properties of insulating material values in different environmental conditions. For this purpose, it was created five sets of composite paint primers with different ratio of mica. Samples were gradually exposed to the environment relative humidity of 0%, 33%, 55%, 65% and 75%. For each environment with a defined moisture characteristics were observed in samples exposed to the temperature of 20 to 50 ° C. The diploma paper analyzed the influence of the mass implementation of mica in each set of samples and placed on the surface structure of samples.
