Sound Module for Evaluation Kit
Priškin, Jiří ; Číž, Radim (referee) ; Sysel, Petr (advisor)
This thesis is dealing with design and putting into operation of sound module for evaluation kit Atmel ATSTK1000. At the beginning, there is an introduction with properties, hardware and software equipment of the evaluation kit which is used for development of embedded devices based on AT32AP7000. The microcontroller AP7000 is a complete system on chip with an AVR32 microprocessor core, containing additional supporting circuits, controllers and interfaces which the core itself does not have included. However, there is no digital to analog converter for audio signal processing. This has led to design an additional module performing this task. A part of thesis describes Intel AC‘97 standard including AC-link interface, which is used for full-duplex data transmission between realized sound module and the evaluation kit STK1000. The sound module is designed as a plug-in card. The last chapter presents the Linux operating system installation process as an SD/MMC Flash memory card boot image creation and test of the sound module under ALSA architecture.

DDS Based High-frequency circuit analyzer
Priškin, Jiří ; Brno), Tomáš Mádr (DCOM (referee) ; Šebesta, Jiří (advisor)
At first this thesis is dealing with the basic principles of network analyzers and afterwards goes to propose conception of a polyscope, as a special type of the scalar network analyzer, designed for magnitude frequency response measurement of two-port devices. As a result of this part of the thesis is the polyscope's block circuit diagram and also selection of key integrated circuits for sweep generator, logarithmic detector and control circuits. As the following part of the thesis is a design of the all basic analyzer's circuits resulting in their schematics diagrams and printed circuit boards, do assembly of all modules and mechanical construction of the instrument and look of the front panel. Some of the tasks is implementation of the firmware and personal computer application able to download measured data from the circuit analyzer via USB and generate chart in Microsoft Office Excel book.
