Tremolo effect with high modulation frequency range
Pazdera, Michal ; Dvořák, Jan (referee) ; Kubánek, David (advisor)
This work was created while designing the dynamic modulation effect „tremolo“. Because there are certain conditions (wide modulation frequency range, precise input of parameters and precise indication), this work is going to be constructed mainly of searching the right components and schematics, especially wide range frequency oscillator with a period from seconds to the frequency of hundreds of hertz, possible digital frequency counter, which serves as a precise indicator, but we will also talk attenuators, amplifiers, driving circtuits or a power circuit. Possible equations, schematics/circuits and their improvements can be found here through simulators Falstad (ideal circuits) and LTspice (real ciruits), also graphs, sheets, calculations. In the end there is also a short description of the two famous tremolo effects from BOSS and Schaller manufacturers. The design was constructed on breadboard, measured into the protocol and experimentally tested using soundcard. Based on those measurements, a model laboratory task for students has been made.

Analog Modular Synthesizer
Klecl, Martin ; Urban, Ondřej (referee) ; Schimmel, Jiří (advisor)
This thesis explores the topic of analog modular synthesizers and the circuit designs used in these devices. The introduction of the theoretical part deals with the basic terminology of modular synthesizers and their history and classification. The thesis also presents and characterizes the methods of producing sound focusing on additive, subtractive and modulation synthesis. From the fundamental components of a subtractive synthesizer, the thesis describes a voltage controlled filter, voltage controlled oscillator, low frequency oscillator and voltage controlled amplifier. The practical part of the thesis concerns design and construction of these components into a single universal Eurorack format module. The results of the thesis comprise measurements of the parameters of each of the basic blocks of the synthesizer module.

Tremolo effect with high modulation frequency range
Pazdera, Michal ; Dvořák, Jan (referee) ; Kubánek, David (advisor)
This work was created while designing the dynamic modulation effect „tremolo“. Because there are certain conditions (wide modulation frequency range, precise input of parameters and precise indication), this work is going to be constructed mainly of searching the right components and schematics, especially wide range frequency oscillator with a period from cca ten seconds to the frequency of hundreds of hertz, and of the digital frequency counter which serves as a precise indicator, but we will also talk attenuators, amplifiers, driving circtuits or a power circuit. Also equations schematics/circuits and their improvements can be found here. In the end there‘s also a short description of the two famous tremolo effects from BOSS and Schaller manufacturers.

Analysis, features and applications of available voltage mode multipliers
Kopeček, Pavel ; Koton, Jaroslav (referee) ; Šotner, Roman (advisor)
This work deals with the analog multipliers, mainly of the voltage multipliers. Also the modifications of current output will appear here. The first part is devoted to a choice several multipliers and a description of their functions, the possible involvement and introduction of the most important catalog values. The next section deals with the simple application that contains at least one of the multipliers. Next was the implementation of selected applications and measure their actual performance parameters. Results are then compared with computer simulations. As final step is done of tolerance and sensitivity analysis of simulated configurations of circuits.

Design and realization of the vocal encoder for audio electronics
Milota, Vojtěch ; Šotner, Roman (referee) ; Kratochvíl, Tomáš (advisor)
This work deals with the design of the vocal encoder, a device used for regressive synthesis of a speech signal using an external carrier signal. Work consists of the block chart, its breakdown and following design of all partial circuit solutions, including simulations in the software environment, followed by design of the printed circuit board and realisation of a prototype of the vocal encoder, followed by experimental measurement of its properties.

Audio signal dynamics processors and their involvement in laboratory teaching
Růžička, Matěj ; Koton, Jaroslav (referee) ; Kubánek, David (advisor)
This master’s thesis describes dynamics processors, their basic building blocks and parameters, as well as the differences between various types of processors. There’s also a description of the design process and the performed simulations of the audio compressor parts. The audio compressor is using the model of the integrated circuit THAT4305. For functionality verification the whole circuit was simulated. Due to the long-term unavailability of THAT4305, the design had to be altered for THAT4315. In the next step the PCB for the compressor was designed, manufactured and the device parameters were verified. Eventually the manual for a laboratory task and an exemplary protocol were formulated.
