Three-channel mixing console
Sůra, Lukáš ; Boušek, Jaroslav (referee) ; Hejátková, Edita (advisor)
This work deals with the design and manufacturing of the three channel analog mixing consol. This console is capable of mixing low frequency signals. After a short introduction and distribution of panels is shown a block scheme and then designed circuit diagram. Each chanel is three-band, it is solved by using the equalizer combined with the logharitmic level controller (fader), the sensitivity controller (gain) and the interception button. The preamplifier and three-band equilizer are used to treat the microphone input. The mixing pult has six stereo inputs, three of them for the line levels signals (line in) and the last three inputs for a portable phonograph treated with pre-amplifiers (phono in). It also has three stereo line level outputs used by the main output (master out), the interception (booth out) and the headphones (headphones out). The output corrections are solved by using the five-band equalizer, which can be bridged. The linear level controller (crossfader) is placed beetwen channels. The logathmic level controller is used to setup the output signal.

Interface for optical pulse detector
Dušek, Filip ; Barcík, Peter (referee) ; Kolka, Zdeněk (advisor)
This bachelor thesis deals with the design, realization, and testing of the interface for the optical pulses detector. The interface consists of 3 parts – the photodetector, the preamplifier, the adjustable source. Supply source for avalanche photodiode includes experimental function for voltage automatic setting with the help of gain measurement. Photodetector is complemented by a wideband amplifier with gain 19dB.
