Electronic system of language education laboratory
Skoumal, Martin ; Bradáč, Zdeněk (referee) ; Zezulka, František (advisor)
This work deals with the creation of electronically controlled audio system for the language classroom. Possible solutions compares analog and digital form. Furthermore, describes the final system that was designed. The resulting system is implemented by analog amplifiers and analog crosspoint matrix. Hardware control is realized by microcontroller and that is controlled from the computer.

Digital voice communication network with status indication
Pobiecky, Michal ; Šilhavý, Pavel (referee) ; Krajsa, Ondřej (advisor)
The main focus in this diploma thesis is to analyse ARM microcontroller ATSAM3X8E, audio codec TLV320DAC3203 and CAN / RS485 bus for communication possibly used in device design. This device's purpose is to establish communicatio between elevator cabin and central control unit. Finally, there is design made for this communication device and measurement of CAN bus speed on H05VVH6 cable.

Electronic Drum Control Module
Doležal, Karel ; Růžička, Richard (referee) ; Šimek, Václav (advisor)
This paper deals with development and construction of an electronic drum module. The purpose of the device is to capture signals from an electronic drumkit and to produce sound accordingly. Firstly, a protoype with no sound output is constructed to demonstrate an ability to capture input signals. Based on its function, parameters for a final device are determined. Then, electronic component selection and design of printed circuit boards is described with an aim to maximalize polyphony and minimize latency of the sound generator. After that, firmware with software mixing algorithm is designed. Lastly, testing and measurement of real device parameters is performed.
