Shaping networks and limiters for educational laboratory purposes
Barč, Andrej ; Domanský, Ondřej (oponent) ; Šotner, Roman (vedoucí práce)
This bachelor thesis deals with design and implementation of shaping diode circuits and double - sided diode limiter of sinusoidal signal for laboratory use in low frequency band. This is a 3-segments and 6-segments shaping circuit with and without active element (without operational amplifier). The circuits form a triangular signal to harmonic signal. The aim of the design was to achieve the least possible distortion of the output signal on the largest frequency range of usability. The functionality of the circuits was verified by measurement and a laboratory protocol was constructed from the measurement result. The measurement results were compared with the results of ideal simulated waveforms.

Transmission of the radiofrequency signal over optical fiber
Barč, Andrej ; Dvořák,, Filip (oponent) ; Barcík, Peter (vedoucí práce)
This work deals with the transmission of optical radiation modulated by a radio frequency signal through an optical fiber. Furthermore, it describes the principles of communication and area coverage. It points out the practical use of components located in the communication chain of this system. Explains the functionality of the properties and the division of individual components. It introduces the benefits and limitations of this system. It further describes the creation of a topology suitable for laboratory measurement of RoF technology. Provides experimental measurement of C-band parameters. Indicates the possible use of RoF technology using a wireless optical link. A part of the work is also a sample laboratory protocol.
