Microcontroller based system for voice transfer
Kapitančik, Maroš ; Kaczmarczyk, Václav (referee) ; Bradáč, Zdeněk (advisor)
The aim of this thesis have to introduce us with digitalized transmission of speech with limited data flow and construct device witch can comunicate on this level. Theoretical part is describing base creation of sound human preception and issues with digitizing. Proposed device uses hardware codec VS1063a. Coding is applied with IMA ADPCM. Scale of incoming analog audio signal can be up to 4kHz. Inside system is controled by microcontroler, witch take care about others parts. For comunication with other moduls is used wireless transceivers module. Software part describes confuguration and selected options of every individual part. Next is explained principle of entire system. For comunication was implemented packet data structure. This implementation raised data flow but saved error state in transmit.

Radio
Matyášová, Hana ; Štětina, Roman (referee) ; Klímová, Barbora (advisor)
The goal of this work is to create a radio station at FFA and to start with building space for sharing audio across faculty. Radio creates a space of possible sharing and collaboration. The activity of content creation, where a collective of people come together, becomes important in this regard. Radio also captures the audio image of FFA through an ever-growing and never-ending archive of music created by current and former members of the academic community. An important point in the development of the work has been the event and broadcast of the Unambitious Studio which dwelled into Environment studio. The Unambitious Studio was based on the author's own research and addresed questions of the nature of the studio and its transformations, forms of ambition. Inspired by the principle of the Unambitious Studio event, the thesis Radio will be presented in the defence on 16 May 2022 with the (Un)ambitious Radio event. Inspired by the principle of this action there will be action (Un)ambitious radio as presentation of master's thesis Radio.

Public radio in the Czech Republic, its current and future position in society from the perspective of millenials
Hanáčková, Kamila ; Groman, Martin (advisor) ; Jirák, Jan (referee)
This thesis deals with the analysis of listening to public radio in the Czech Republic among millennials. It wants to find out their listening habits and behaviour, their motivation for listening and their perception of the current position and future role of public radio in society. The theoretical part of the thesis explains the basic concepts that are essential for the thesis, introduces the methodology and content of the whole thesis, and also presents the theoretical approaches of cultural studies on which the thesis is based. These are mainly based on the concept of active audience, the theory of selectivity and the findings of the so-called Birmingham School. It briefly describes the historical development and role of radio in the Czech Republic and its current form. In the practical part of the thesis, it interprets its own empirical research, what it consists of, how it was conducted and what its conclusions are. This was carried out using a qualitative method and in-depth interviews with twelve respondents, asking twenty open-ended questions that explored participants' listening, motivations and perceptions of Czech public radio. Using the method of grounded theory, categories were created through open, axial and selective coding, which could be used to elaborate a central category, on...

Migration of telemetric narrowband radio networks to the IP standard
Stupka, Richard ; Lattenberg, Ivo (referee) ; Maršálek, Roman (advisor)
This bachelor’s thesis deals with the innovation of narrowband telemetry radio networks to the IP standard. This involves the modernization of old radio data networks that do not use the IP standard or are nearing the end of their life cycle. Renovation has a great benefit in terms of performance, reliability, and security. This modernization is achieved through migration, which means upgrading the old technologies to new ones. The objective of this thesis was to develop theoretical analysis and a technical procedure for network migration. It was deals with the currently used technologies and utilized components, parameters of individual network nodes, the actual design of the migration technical solution and network preparation. After the analysis and technical solution for migration had been performed, the proposed migration solution through simulated operation in a laboratory environment was verified. Based on the obtained information, configuration files for real-world usage were created, radio signal coverage in the field was verified and the communication capability in the newly built RipEx2 network was tested.

The manifestations of technological determinism on the selection of news topics in ČT24 and ČRo Radiožurnál
Bečková, Kateřina ; Jirků, Jan (advisor) ; Trunečka, Ondřej (referee)
The diploma thesis entitled The manifestations of technological determinism on the selection of news topics in ČT24 and ČRo Radiožurnál seeks an answer whether the choice of news topics in TV and radio is influenced by the available technologies in each of the media, and whether they eventually choose different events to cover. The theoretical part describes concepts of gatekeeping, news values and also technological determinism. In the practical part then the author analysed three days in broadcast of the chosen media, in each it was two-hour segments around the main news at noon and in the evening. Selected topics, that ČT24 had and Radiožurnál did not, have been later analysed by semiotic analyses in order to find whether the visuals were the factor why the event was not presented by the radio. Context of the findings were given by six semi-structured interviews with journalists form both radio and television. From all the data obtained, it is evident that the television had dozens of topics more per day, caused by the time space given to the news reporting. Unlike Český rozhlas Radiožurnál, ČT24 focused significantly on the visual side of events, which could be the reason why editorial board may reject a topic proposed by the reporters.
