Digital microphone signal processing
Vykydal, Martin ; Macho, Tomáš (referee) ; Havránek, Zdeněk (advisor)
The aim of this work is to implement digital filters into programmable gate array. The work also includes a description of the MEMS technology, including comparisons with the technology of MEMS microphones from various manufacturers. Another part is devoted to the Sigma-delta modulation. The main section is the design and implementation of digital CIC and FIR filters for signal processing of digital microphone, including simulation and verification of properties of the proposed filter in Matlab.

Colour Noise Generator
Křivánek, Tomáš ; Rajmic, Pavel (referee) ; Frenštátský, Petr (advisor)
The main purpose of this bachelor thesis is explanation of „colored noise“, such as pink, brown, blue and more. There are completely subscribed coloured noises in this work, includig their importance and use for measurement in electroacustic and sound technology. Practical part of this thesis is focused on generating colored noises in Matlab, where we mainly work with model frequency spekter, frequency response and FIR filters.
