AM transmitter for experimental purpose
Kundel, Petr ; Urbanec, Tomáš (referee) ; Prokeš, Aleš (advisor)
The bachelor thesis deals with the problem, design and implementation of an analog AM transmitter for experimental purposes. In the thesis, the individual circuit blocks are analyzed, the block and circuit structure of the transmitter with modern components is designed, which is subsequently implemented after simulations. The implementation of switching amplifiers minimizes the power dissipation and thus the circuit achieves high efficiency.

Digital audio amplifier with universal inputs
Svadbík, Pavel ; Stifter,, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
This diploma thesis deals with digital audio amplifier with universal inputs and its design. The first part describes modulation and audio formats for audio electronics. The thesis contain design of a block diagram of the digital audio amplifier and describes the requirements for functional blocks. As a basic device for audio signal processing was choosen integrated circuit STA326. The thesis continue with circuits design for each blocks with a description of their principles. The next section describes the construction and firmware for microcontroller. The last part of this diploma thesis is targeted on the presentation of the measured parameters of the amplifier. The conclusion summarizes the results that have been achieved and advantages and disadvantages of the digital audio amplifier prototype.

Design of switching-mode audio power amplifier
Svadbík, Vít ; Sutorý, Tomáš (referee) ; Brančík, Lubomír (advisor)
This work describes the design of audio amplifiers operating in switching mode. The first part describes basic principles of the power stage switching concept. There is described differences between classes of amplifiers according to technology. The second larger part includes design and construction of the switching amplifiers. Design is implemented, including the preamplifier and power supply. Power supply works in switching mode. The measured parameters of the proposed facility are given in the last part.
