Analysis of time-frequency characteristics of signals
Vitouš, Jiří ; Ředina, Richard (referee) ; Poměnková, Jitka (advisor)
This thesis focuses on time-frequency analysis of discrete signals. The aim of this work is to compare the most well known methods for spectro/scalegram estimation. The two main topics discussed are: The compromise between time and frequency resolution and the effect of noise in input data on the quality of estimated spectrograms. To achieve this a database has been created. This database consists of real and artificial signals on which the analysis can be performed and evaluated. This database is used in created demonstration application. This application is also used in a created laboratory task.

Laboratory model "Liquid Tanks" innovation
Škapa, Antonín ; Fiedler, Petr (referee) ; Kaczmarczyk, Václav (advisor)
This bachelor thesis deals with innovation of laboratory exercise „Tanks“. There are described the most used sensors and actuators including means of connection to PLC. The ANSI/ISA S88 and ANSI/ISA S95 standards are depicted as well with emphasis on key performace indicators. Technological tanks are documented here including industrial use examples since the laboratory exercise „tanks“ works with model of a technological tank. Furthermore there are briefly analyzed PLC programming languages, especially SCL. In the end, there is the laboratory exercise assigment with technological scheme and attention of error states.
