Transient Effect at the Output of a Linear Dynamic System Controlled Pulse-Width Modulation
Petera, M.
The goal of this work is to determine the size of overshoot produced at the output of a linear continuous second order system controlled by pulse width modulation. This work contains the calculation of the output signal response of the system in the time domain using the Laplace transform. The calculations of the amplitude of the output signal based on the pulse width modulation and system parameters are performed in this work. Finally the possibilities were given to determine the suitable period of pulse width modulation for required ripple. All the important calculations were compared with the simulations in the MATLAB-SIMULINK program and with the measurement at the real inertia second order cell.
Measurement cables and connectors for audio
HAVEL, František
This thesis deals with design and practical implementation of a comprehensive test for measuring and comparing the performance of audio cables and connectors used in audio technology. The theoretical work is the part that deals with the signal, sound, cables and connectors and methods of measurement used. In the practical part are results and comparison of wide price range instrumental cable. Studied parameters are: the electrical resistance of the cable, the capacity and inductance. Was also been studied the affect of the cable using frequency analysis. It was created overview table, which summarizes the findings.
Microwave interconnection, realization, used technologies and operation
OLIVA, Radim
This work deals with generally questions of microwave connections. In work we found information about wire-less transfers dividend in line with frequence ray inclusive abstrakt of technology. Also there are general information about wireless transfer, used modulations and data security during the transfer. In praktical part we located concrete project of concept data trace, on which I worked and took part on realization.
