Master’s thesis deals with design and practical realisation of electronic circuits, which are needed for assembling of DRM signal transmitter for ham short waves bands. There is presented DRM standard as well as there are described the differencies between DRM for radio broadcast and for ham using. There is described design of input audio circuits, modulator, mixer, local generator, amplifier and filters. Principle of used SSB modulator is based on phase method, often called Tayloe modulator. This principle is analysed in detail including mathematical description, which was derived. It is possible to control the transmitter by program running at computer, communication takes place via USB. There is described establishment of communication in this work too.

Electronic books at VŠE
Saska, Filip ; Koubský, Petr (advisor) ; Šperková, Lucie (referee)
The master dissertation Electronic books at VSE is focused on analysing the opportunities of e-books in the environment of VSE. The aim is to describe the current state of different study materials used at VSE and to explore different ways of improving them using e-book technology. The dissertation briefly describes various attributes of e-books with stress on the relevant attributes -- the possibility of inserting notes, bookmarks, multimedia and interactive content. Also the possibility of editing the content and sharing resulting changes with other students is a key attribute. The dissertation then moves on to describe the different kinds of study materials that are in use at VSE. The second half of the dissertation builds on previous analysis of the study materials and introduces a hypothetical optimal state, which could result from implementing e-book technology. This state is the answers the question of what is actually possible to achieve. The next chapter in this half is the technical analysis, which answers the question of how is it possible to achieve the suggested hypothetical state. The conclusion of this dissertation answers the questions whether the proposed solution is a viable candidate for implementation. The results of this dissertation could be used as a guideline for the project of implementation of e-book technology in the environment of VSE.
