Doppler's sensor beat freqeuncy proccessing
Dušek, Martin ; Macho, Miloslav (referee) ; Fuchs, Michal (advisor)
This work is engaged in ways of objects speed measuring mainly helped by Doppler Effect. The sensor HB410 is described in this work and its possible elaboration output heterodyne analog signal. The calculation of objects speed is deduced from frequency of heterodyne signal. In this work is projected circuit solution for elaboration of analog signal and its digitalization. Available types and nature of microcontrollers which are elaborating digital signal and communicating with PC are summarized in this work. In the last chapter is described microcontroller's driving software and PC software for speed measure.

Universal Tester of Tyco Fire panel
Vítek, Ladislav ; Kalina,, Emil (referee) ; Šteffan, Pavel (advisor)
This work is aimed on design of a device for testing of fire detectors and various components of fire detection system, communicating with the fire panel over a fire bus or a loop. The device generates voltages, supplying the detectors, as well as communicating over the bus generating communication waveforms and performing detection of responses measuring voltage and current on the connection. The loop signal is processed by the developed unit and data or result sent to a PC utilizing USB or RS232 connection. All the parts of the equipment are galvanically isolated to the loop circuit.

Design and development of sigma-delta AD converter in switched capacitor technique
Forejtek, Jiří ; Fujcik, Lukáš (referee) ; Háze, Jiří (advisor)
The work deals with the design of novel high order sigma-delta AD converter using switched-capacitors approach. Model of the ideal and real architecture of the third order sigma-delta modulator was designed in MATLAB SIMULINK. The comparison of the ideal and real model of sigma delta architecture is described in this thesis. On the basis of simulation results in MATLAB SIMULINK the stages of modulator on transistors level in CMOS technology were designed. Fully differential operational amplifier, switched capacitor integrator, summing amplifier, comparator, one bit digital to analog converter and nonoverlapping clock generator were designed. The circuit of third order sigma-delta modulator was simulated in CADENCE. Layout of operational amplifier and switched capacitor integrator was made. Through the use of MATLAB was designed decimation filter as well.
