Generation of Voltage Wave by Impulse Generator
Poloni, Miroslav ; Krbal, Michal (referee) ; Pelikán, Luděk (advisor)
The presented bachelor thesis deals with the problems and functions of impulse voltage generators. The theoretical part describes the functions and various connections of the impulse generator, types of impulse voltage, tests and test procedures. In the practical part of the work, theoretical knowledge in the form of simulations was verified. The simulations were performed in the LTspice program from Linear Technology, where the impulse generator model was made. Simulations were then performed on the given model of the shock generator, from simpler ones such as the dependence of the size of the load capacity to the inductance connected in parallel. The results of all simulations should bring benefits and ease in real shock generator tests

Audio signal processing in electronic circuit simulators
Paluřík, Pavel ; Herencsár, Norbert (referee) ; Kubánek, David (advisor)
This bachelor's thesis deals with the simulation of electronic circuits with a focus on the processing of audio signals. At the beginning of the work a detailed procedure and instructions for work in the selected simulation program LTspice are described. The program is free to download, so anyone can try the simulations. The import, processing and export of audio files are also described. The sound of an electric guitar, a spoken word in a male voice, rock and synth recording are then discussed in more details. The last part is devoted to detailed examples of the functions of the tested circuits. The circuits tested are high-pass filter, diode limiter and effect pedal Fuzz Face which is compared with real constructed unit. The verification of the sound from the computer simulation is subjectively evaluated at the end of the work considering similarity of simulated and real recorded audio from Fuzz Face.

Optimization of AC signal voltage amplifier
Vaculík, Lukáš ; Sitta, Michal (referee) ; Šedivá, Soňa (advisor)
The Bachelor thesis deals with the analysis of the voltage amplifier and with simulation of its behavior using program LTspice. The basics for working in this simulation program are also described. The content of thesis is also a measurement of the actual implementation of the amplifier for comparison with the performed simulations. Subsequently, there are outlined possible solutions how to optimize the scheme in order to achieve the best possible results in the monitored parameters, especially the distortion and amplitude of the output signal in the thesis. The scheme was presented by Meatest, s.r.o., where the amplifier is part of a multifunction calibrator. Theoretical part, which serves as an introduction to the issue, describes the components and introduces important concepts, is also included in the thesis.

Optimization of voltage amplifier
Malík, Luděk ; Bartoň, Jan (referee) ; Šedivá, Soňa (advisor)
This bachelor thesis concerns the simulation and optimisation of a voltage amplifier as a part of a multifunctional calibrator 9010, which has been recently introduced by Meatest s.r.o. company. The simulation is executed with LTspice software. LTspice itself and the basics of its usage are also described in this thesis. Furthermore, this thesis contains the theoretical analysis of used components and their connetions. The thesis also depicts the schematics of the above mentioned voltage amplifier supplied by the Meatest s.r.o. company. The thesis contains measurements of selected properties of the voltage amplifier from the 9010 calibrator and their comparison with the results of the simulation. The optimisation concerns these selected properties and compares them to the original qualities of the calibrator 9010 voltage amplifier.
