Comlete design of class D power amplifier
Bistrý, Jan ; Šotner, Roman (referee) ; Petržela, Jiří (advisor)
In this bachelor's project was at first described a principle of class D power amplifiers. There was performed a characteristic of particular blocks. In the concrete steps were described particular solutions of these amplifiers with PWM driver, amplifier as an IC chip and were described advantages of this topology. It was performed an overview of the modern integrated amplifiers which are currently available. According to further requirements of this bachelor's project were designed a scheme and a board of printed circuit for this amplifier. In more details were described possibilities of output LC filter and performed its simulation. At the conclusion of this project was performed a laboratory measurement of realized amplifier which verified its performance and compliance with engaged parameters.

Laboratory module of class D amplifier with PWM modulation
Barcík, Peter ; Petržela, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor’s thesis describes basic functional blocks of class D audio amplifier. Project also discuss about design of module class D audio amplifier with PWM modulation. As this audio amplifier is going to be a laboratory module, it is necessary to divide design into designs of individual functional blocks. Finally project describes design of output LC filter which is also simulated in PSPICE program. This thesis include complete construction details. Measurement results are shown in standard protocol.

Graphics Intro 64kB Using OpenGL
Pinter, Jan ; Španěl, Michal (referee) ; Herout, Adam (advisor)
This paper deals with graphics intro (demo) 64 kB creation issues. It analyses and describes problems involving effective use of minimum data space assigned and presents basic techniques used with those specific types of programs as mentioned above. It also describes a way of specific, interesting graphic effects and elements realization, their possible optimization and visual improvement.
