System for Precise Measurement of Electrical Length of Coaxial Cables
Podr, Michal ; Polívka,, Milan (referee) ; Šebesta, Jiří (advisor)
This thesis describes a study of the measuring methods determining the electrical length of coaxial cable without using a vector network analyzer. First, a general theory of management and its various parameters is briefly discussed. This section is focused more specifically on the coaxial cable and its parameters. The next part is graphically analyzed process considerations in the design of measurement methods and outlined the block structure of the system. The third section describes the working process, prototype testing of the bridge, its measurement and design of the measuring system. In the fourth part the software is described. In conclusion, the results of the work are discussed, accuracy of the measurement system, the obtained parameters chosen with regard to the principle of the measurement system and the overall evaluation of the applicability in practice.

Design of class AB stereo audio power amplifier
Podr, Michal ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
This thesis describes the design of a complete amplifier operating in class AB. It contain two power amplifiers with working in the bridge mode correction amplifier with volume control, bass, treble, and also with the choice of loudness. Preamplifier with three different inputs and the choice between stereo and mono modes.
