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.

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.

Design and realization of the pedal effect on Arduino platform
Gajarský, Tomáš ; Schimmel, Jiří (referee) ; Krajsa, Ondřej (advisor)
The topic of my bachelor’s thesis is the design and the construction of the pedal effect used by the Arduino Due, which is supplemented by the possibility of controlling through the internal web interface, which is mediated by the modul Arduino Ethernet Shield. The following effects are included: echo, tremolo, vibrato, chorus and flanger. For editing the guitar signal in order to interact with AD microcontroller converter, is used the input filter preamplifier circuit. In order of editing the output signal from Arduino is used summing and filtring output circuit for the guitar amplifier. The basic component for these circuits is operating amplifier OPA1644. The goal of this thesis was to create the proposal of the connection schemes, printed circuit board, the program code of the microcontroller, simple web page, as well as the construction and the measurement of the pedal effect.

Delay and Tremolo Guitar Multi-Effect
Blažek, Jiří ; Hanák, Pavel (referee) ; Kubánek, David (advisor)
This work deals with the design and construction of a delay – tremolo type multi-effect unit. In the theoretical part, it thoroughly studies the functioning of both types of effects in detail. It further focuses on circuit solutions and provides a detailed description of the schematic. The work subsequently verifies the functionality of these schematics in the Ltspice simulation program. Then the simulation results are compared with measurements on a breadboard. In conclusion, the work focuses to the PCB design and the construction of the multi-effect pedal.
