Mikroprocesor controlled equalizing repeater.
Požár, Marek ; Fedra, Zbyněk (referee) ; Kovář, Jan (advisor)
The correction amplifier is included in many audio applications. Its use is mainly in the regulation of volume, height, depth, balance settings, channels, and extended versions as well as more band equalizer. There are the simpler versions such as home movies, personal computers, car. However, there are even more demanding applications, where the correction amplifier extended to listening to different bands. Already mentioned band equalizer, which is now part of almost every recording studio. Applies even when the sound of concerts. This project deals with its links with the microprocessor and then control the PC via USB. Utility sends the PC via USB management factors in the microprocessor data, which is further processed and under control of the data correction circuit amplifiers using the IIC bus.

Autonomous USB datalogger
Románek, Karel ; Sutorý, Tomáš (referee) ; Kolka, Zdeněk (advisor)
This thesis treats concept of autonomous temperature, relative humidity and pressure USB datalogger. Also there is explained datalogger function, hardware design with respect on device consumption and design of chassis. Furthermore, there is described communication protocol for control and reading out data by the PC. Furthermore, there are described firmware drivers for some used components and modules for USB communication, RTC and data compression. Lastly there is described software which is used for datalogger configuration and data read out.

Programmable signal generator
Románek, Karel ; Kolka, Zdeněk (referee) ; Tošovský, Petr (advisor)
This thesis treats designing and the implementation of the Programmable Signal Generator which generates analog and digital signals using microcontroller. It describes the function of the generator, component selection and their implementation into the circuit, for example design of circuits for digital to analog conversion and the final adjustment of generated analog signals (amplification and offset setting). It also describes the communication protocol between the generator and personal computer using USB HID class, the development of graphical user interface and microcontroller firmware. Lastly, the measurement results are presented and compared with simulation results.
