THD Analyzer
Ha, Tuan ; Drexler, Petr (referee) ; Mikulka, Jan (advisor)
This thesis deals with design of a THD analyzer for audio frequency. In the interduction, there is a description of methods of THD calculation and realization of THD analyzer. Suitable computing platform must be chosen with capability to process audio data. The expansion board is designed for audio acquisition. Part of this design is complete program that is capable of displaying spectrum and computing THD.

Design of anti-aliasing filter for discrete-time delta-sigma modulators
Vogel, Vojtěch ; Háze, Jiří (referee) ; Kledrowetz, Vilém (advisor)
This work deals with the design of a second order anti-aliasing filter with a cutoff frequency in the order of hundreds of kHz using the switched capacitor technique. The use of this technique allows the design of accurate and tunable analog circuits without the use of resistors. In this work, the design of analog switches is described. Furthermore, the various circuits required for the design of the filter in the onsemi I3T80 technology are proposed.

Adaptive antialiasing frequency filter
Sovadina, Václav ; Murina, Milan (referee) ; Sedláček, Jiří (advisor)
The aim of this project is to become acquainted with the Bessel approximation function and to present the possible connections of the adaptive antialiasing filter. Then, cascade and partition filter realizations are designed and their computer analysis are carried out. Furthermore, the thesis deals with the options of electronic realignment of filters. A common connection of digital potentiometer along with the block diagram of the whole mechanism are described. The next part presents a construction of the analogue part of the filter, measuring of its real characteristics and the control circuit for the analogue part.

Control of water supply for a house
Chvátal, Michal ; Richter, Miloslav (referee) ; Macho, Tomáš (advisor)
The diploma thesis deals with the design and implementation of the system that will control the water supply for the family house and its garden. The system aslo allows you to store a history that can be viewed via the web interface. The web interface also allows you to set system parameters and monitor the current status.
