Microcontroller-based graphic equalizer
Šmotek, Jiří ; Šebesta, Jiří (referee) ; Dušek, Martin (advisor)
This bachelor's thesis deals with problems of correction of audio-signal by help of equalizer. The first part discusses the fundamental properties of electronic filters. The second part describes graphic equalizer and its schematics. A simulation of this suggested connection is executed in the PSpice software. Furthermore, the circuit diagram is presented and the proposal of PCB design equalizer is realized using the digital potentiometers instead of the classic potentiometers. Following part is then focused on description of a programme for the microcontroller and PC. The last part finally presents the measurement.

Equalizer with loudness regulation for laboratory measurements
Karkoška, Jan ; Šotner, Roman (referee) ; Kratochvíl, Tomáš (advisor)
This bachelor’s thesis deals with a draft and construction of the design of equalizer with loudness regulation for laboratory measurements lessons and also simulation of individual parts in the program LTspice. For design was used bandpass correction with series resonance circuits. All bands are tuned to a frequency f0 with a degree of ± 12 dB. Thesis includes block diagram, design of equalizer in detail, scheme of equalizer with physiological regulation and the design of printed circuit boards.

Basscomb design
Gomola, Roman ; Balík, Miroslav (referee) ; Káňa, Ladislav (advisor)
The following text describes the design basscomb intended to strengthen and reproduce bass. In individual chapters is described as electrical and mechanical design of the combo, which is actually a type of enclosure port tube with built-in amplifier and the corrective circuits. The first part is devoted to a description of the speaker MONACOR GF-650 and amplifier design based on the IO LM 3886, which includes a power supply of the entire facility. The next section describes the correction amplifier, solutions five-band octave graphic equalizer. In penultimate section describes the selection and design of the baffle, its production and finishing. The last section is devoted to the measurement of manufactured.

Big Muff Type Distortion Guitar Effects
Beránková, Tereza ; Balík, Miroslav (referee) ; Kubánek, David (advisor)
Presented thesis is focused on construction and functionality of distortion effects and equalizers. It investigates the possibility of their usage in guitar distortion effect called Big Muff which consist of several blocks. One of them is tone control and this thesis intention is to implement equalizer instead. Part of this thesis is also creation of a laboratory task focused on measuring and understanding to this guitar effect
