Laboratory equiptment for GPIB bus control interface
Ondrák, Jan ; Háze, Jiří (referee) ; Pavlík, Michal (advisor)
The project deals with a USB–GPIB converter, extended by two analog inputs with voltage range from -10 V to +10 V. The converter will be used in combination with the device EG&G Princeton Applied Research - Lock-in Amplifier 5208 and personal computer equipped with USB. The converter is controlled by PC via programmed application and will be able to control by the Lock-in Amplifier 5208 and also read the voltage on the converter analog inputs.

Stereo microphone preamplifier with integrated ADC
Tóth, Péter ; Šotner, Roman (referee) ; Kratochvíl, Tomáš (advisor)
he aim of this work is to design a mobile microphone preaplifier with integrated ADC suitable for in field work. In the intruduction a general overwiev is presented about the history of sound recording and it also deals with the parameters of the devices designed in this work. In the next chapter the contruction of each module is described.

The realization of measurement workplace for simulation and testing of AD converters
Panáček, Jiří ; Fujcik, Lukáš (referee) ; Háze, Jiří (advisor)
The objective of this thesis is a design of a development kit, which is used in laboratories during the lessons of Theory of analog to digital conversion subject. This device is adapted for basic measuring and understanding of digital to analog (D/A) and analog to digital (A/D) converters and contains sigma-delta A/D converter made of basic elements, D/A converter with R-2R resistor net, active low pass frequency filter (Sallen-Key), PWM generator, SAR A/D converter with 16 b resolution, reference voltage source and module for measuring integral and differential nonlinearity of A/D converters. The modules are available connect to each other via jumpers and they are driven by microcontroller. This solution gives various modes of operation, which can be selected by user via buttons. Development kit has five BNC connectors for securing connectivity to an oscilloscope or a signal generator. The device also contains universal serial bus connectivity for use with personal computer or laptop, which is really useful with Matlab software for automation processing of measuring.
