Audio Pre-Amplifier for Laboratory Measurements
Friml, Vilém ; Hanák, Pavel (referee) ; Kratochvíl, Tomáš (advisor)
This thesis deals with a design of audio pre-amplifier with fixed frequency filters and a choice between amplification using integrated circuits and solidstate circuit. The thesis includes a design of attenuation circuit, an amplifier with an integrated circuit, an amplifier with transistors, a RIAA filter, a speech filter, a physiological filter, a rock preset filter and a power supply circuit. The thesis describes design of the circuit board, solution of oscillations of the amplifier with transistors and a measurement of the constructed device. The aim of the thesis is the design and construction of laboratory equipment.

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.
