Software for Processing of Sound Level Meter Data
Kříž, Petr ; Schimmel, Jiří (referee) ; Kurc, David (advisor)
This thesis deals with the measurement and evaluation of noise. Thesis summarizes the basic concepts of acoustics and describes methods of measurement and evaluation of noise, focusing on measurement uncertainty. Part of this work is the implementation of software for processing of sound level meter data NTi XL2 in Matlab including practical examples of its use.

Automation of Noise Measurements Using XL2 Sounl Level Meter
Švihálek, Filip ; Číž, Radim (referee) ; Schimmel, Jiří (advisor)
This bachelor´s thesis focuses on noise measurement, characterizes used quantities and uncertainties due to the measument of these quantities. The goal is to develop application, which will automate measurement with sound level meter XL2. Automation will use text output of the XL2 and modul for Remote Measurement. Application is developed in development environment Visual Basic for Applications.

Measurement problem of low AC voltage
Balázs, Ladislav ; Jakubík,, Petr (referee) ; Havlíková, Marie (advisor)
The thesis deals with a problems of measuring small alternating voltage. The aim of the thesis is to explain in general problems of influences on measurement of small alternating voltage and to carry out a concrete measurement according to instructions of CMI. In the next part the thesis deals with the problems of uncertainties for measurement of small AC voltage and a concrete calculation of uncertainties has been made for measurement made in the first part of this thesis.
