Synchronized sources of clock signals
Florián, Antonín ; Lazar,, Josef (referee) ; Drexler, Petr (advisor)
This thesis deals with design of synchronized sources of time signal. The first part of the thesis deals with the theory the crystal resonators, crystal oscillators and PLL. The second part of the thesis deals with the crystal oscillator with 10MHz frequency. In the oscillator is use of SC cut crystal. The third part of the work deals with method of synchronization. To synchronization is use of PLL.

Estimation of equivalent circuit parameters of a piezoelectric resonator
Ryšavý, Lukáš ; Majzner, Jiří (referee) ; Sedlák, Petr (advisor)
In this thesis, a simple measurement setup including control software is designed to estimate the parameters of Mason electrical equivalent circuit for piezoelectric resonators. Direct measurements can evaluate variables, such as mechanical quality factor, parallel resonance, serial resonance and serial resistance. These variables are used to estimate remaining parameters. The software is implemented in C++ Builder. Experimental study and verification were carried out on several quartz crystal and piezoceramic samples. The measurements are in good agreement with simulations as it is illustrated by a low value of relative error. The measurement setup will be used for scientific purposes of Dept. of physics FEEC BUT.
