Audio power amplifier 2 x 500 W
Petrgál, Filip ; Brančík, Lubomír (referee) ; Hruboš, Zdeněk (advisor)
This bachelor’s thesis deals with low frequency power amplifier, distribution, and involvement of important parameters. Furthermore, the second deals with the preamplifiers, power supplies, amplifier circuits protections and other additional modules. Elaboration includes simulated proposals to address preamp, power amplifier output stage as well as protection circuitin PSpice program. Proposes that these modules is shown in the detailed diagramdescribing the components.

Stereo audio power amplifier with microcontroller
Filko, Patrik ; Götthans, Tomáš (referee) ; Brančík, Lubomír (advisor)
This bachelor thesis deals with designing stereo audio power amplifier, which specified functions such as control of volume, depths, treble and balance, are contoled by 16-bit microcontroler with digital potentiometers. Setting those functions is pictured on simple LCD display. Opted amplifier is easy to control ergo it finds use in wide spectre of audio devices such as ampliffing input signal from transmission audio media player or audio signal in television devices. Used design is able to be realized of easy to get components.

Class D audio power amplifier for bass guitar
Appel, Daniel ; Petržela, Jiří (referee) ; Brančík, Lubomír (advisor)
The main goal of this project was a synthesis of audio power amplifier and preamplifier for bass guitar with features suitable for this kind of instrument. The project was divided into 6 parts. The first part is a brief introduction to classes of power amplifiers, the second part is about function of blocks of which the class d audio power amplifier consist. In the third part the designed circuits and their properties are discussed. The simulation of circuits in PSICE are also included in this part. The design of power supply unit is discussed in fourth part. In the fifth there is design of chassis and other mechanical constructions. In the sixth part, there are results of experimental measurements of the amplifier prototype. In the appendix of this bachelor thesis are enclosed the schematics, printed circuit board designs, and photographic documentation of amplifier prototype.

D class audio-amplifier with digital and remote control
Petrgál, Filip ; Kovář, Jan (referee) ; Šotner, Roman (advisor)
The contents of this thesis is design of audio power amplifier in Class D with fully digital control and remote control and is divided into two parts . The first part is devoted to the basic principles and theory of key elements of the entire amplifier. The second part consists of a complete description of the design and construction of a power amplifier, digital control with remote control, a spectrum analyzer, equalizer, preamp VU meters and complete power supply. Each proposal contains a detailed analysis of the solutions supported by simulations and software. For individual parts have been completely measured p arameters.
