All-pass filters based on modern functional blocks
Horák, Ondřej ; Petržela, Jiří (referee) ; Dostál, Tomáš (advisor)
The present thesis is focused on all pass filters. The principle of all pass filters, their properties, the design of nth degree of these circuits will be analysed in succession and then some of functional blocks, by which these structures can be made, will be described. After that, the allpass filters will be designed and simulated in program OrCAD PSpice. First of all, the analysis will be performed with ideal components, then with real components. After that, the sensitivity and tolerance analysis will be made and the influence of parasite effects on circuit parameters will be examined. Once the experiments are finished, the design of Printed Circuit Board's (PCB) will be realized. Circuit showing the best parameters will be chosen for the design.

Laboratory equipment aimed on the all-pass filters
Lokaj, Jakub ; Šotner, Roman (referee) ; Petržela, Jiří (advisor)
Theme of bachelor thesis is design and realisation of allpass filters. It consists of using pasive and active components in design of allpass filters and followed by realisation in laboratory equipment. Functionality was verified in simulating software LTspice and SNAP3v2. In real implementation were used integrated circuits such as TL071, AD844 and LT1228 for CCII+, OTA and design with op-amp. This bachelor thesis includes concept of laboratory equipment, where will be compared functionality of allpass filters with simulated results
