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.

Design of class AB stereo audio power amplifier
Zatloukal, Tomáš ; Polák, Ladislav (referee) ; Brančík, Lubomír (advisor)
The following work deals with design of class AB low-frequency amplifier, which is appropriately supplemented by correction Pre-amplifier and inrush protection circuit. The original schematic from prof. Leach was edited to fulfill task and to be easily completed from discrete components. The result of this work is the final design of power amplifier and correction pre-amplifier, protection circuit for speakers and power supply. As a next part, the design of printed circuit boards will be described together with assembling and mounting of boards in a construction box. Power amplifier will be verified by simulation and hardware measurements.

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.

The construction of a vacuum tube amplifier
STREJC, Jakub
The presented thesis describes the construction of a tube amplifier in both theoretical and practical ways. The aim of this work was to construct a functional tube amplifier with an output of at least 2 x 20 W. The first part of the study describes the theoretical background of tube amplifiers which are recognized for their characteristic sound. Wiring diagrams for each block and other functional blocks of the amplifier, such as headphones or VU meter connections, are discussed. The last part of the thesis focuses on the actual realization of the tube amplifier.
