Recoil forces measurement after shotaVibration Test Stand
Rozum, Stanislav ; Kubinec,, Peter (referee) ; Frýza, Tomáš (advisor)
The thesis describes design and construction of vibration generator driver. The device is controlled via standard Ethernet interface and allows user to change parameters of generated function in PC application which reads and evaluates frequency and amplitude from real-time measured data while the test is running. In the introduction, vibration tests and choice of generators and power amplifiers are described. Next part is focused on every aspect of the hardware design. Last two chapters implement firmware for all three microcontrollers and software for PC application.

Design and realization of D class audio amplifier controlled by microcontroller
Dobesch, Aleš ; Frýza, Tomáš (referee) ; Adamec, Filip (advisor)
The aim of the bachelor’s thesis is to design and construct D Class power amplifier of small proportions using modern integrated circuits. Implement a control software and measure parameters. Thesis describes principle of D Class power amplifiers, choosing suitable components and complete hardware device solution. Control unit is provided by microcontroller AVR ATmega164PA. This power amplifier is extended with radio remote control and effective box.

Design of switching stereo audio power amplifier
Konečný, Jiří ; Papica, Petr (referee) ; Brančík, Lubomír (advisor)
This text analyzes characteristics of audio power amplifiers in class D. The emphasis is placed on more detailed analysis of modulators, drivers, connection topology of power transistors. In the next section of text are analyzed available integrated circuits of power amplifiers in class D which are manufactured by world producers. The last part describes design of all parts of amplifier in class D with discrete components and also of power supplies. According to the plans, the individual parts are made. All parts are tested by measurements and results are evaluated.
