Digital equalizer with dynamic range compression
Šafer, Radim ; Kováč,, Michal (referee) ; Brančík, Lubomír (advisor)
The aim of the thesis is to create a digital equalizer with dynamic range compression. The master's thesis is focused on the comparison of functions and parameters of individual digital processors which are given entirely for sound signals processing. It contains the detailed analysis of singular blocks used for signal processing in the circuit AD1953 and possibilities of control over programmable parametres of those blocks by a user. This thesis also contains a comparasion of the chosen A/D converters together with a description of the UDA1361TS circuit. A designed functional diagram of the final device is introduced as well. Thereafter possibilities of controling the individual blocks in the signal processor are mentioned. The final design of the digital equalizer is also introduced along with a description of software essential to a successful control over the processing of the signal in the AD1953 circuit. This thesis also describes a construction of the digital equalizer and involves results of the chosen measurements.

Loudspeaker design for home environment
Šafer, Radim ; Schimmel, Jiří (referee) ; Kratochvíl, Tomáš (advisor)
The subject of my bachelor‘s thesis is a design of the loudspeaker for home listening. Foremost I focused on simulations of the loud-speakers, which I use to a design itself. The loudspeaker is a two-way and stereophonic, which is optimised for a woofer Beyma 6B30/P and a tweeter Beyma T2010. The enclosure is closed, made of the M.D.F. material. The vibration damping is ensured by a polyester damping cottonwool. The maximum standardised wattage of the loudspeaker is 50 W, nominal impedance is 8 ?, internal capacity is around 15 litres, sensitivity 90 dB and weight 10 kg.
