Measurements by sampling computer card - laboratory task
Tomaštík, Roman ; Havránek, Zdeněk (referee) ; Dřínovský, Jiří (advisor)
This thesis focuses on the measurement with the help of sampling cards and determination of the basic parameters of the measured signal. There will be described basic characteristics of the used card Alazartech ATS860- 256M and brief description of the programming languages which will control the cards. In these environments there were the created driving programs for the operation of these cards. Main measuring program was created in the language C\C++, that shall work as oscilloscope and the same time as spectral analyzer. This programme will determine basic characteristics of the measured signal. Further there will be created simple preparation for memasuring with this card. In the conclusion of this thesis will create instrutions for laboratory exercise.

EMD instruments and electromagnetic mmunity
Mikula, Dalibor ; Buchta,, zdeněk (referee) ; Havlíková, Marie (advisor)
The work deals with implantable devices and possibilities of interference of elektromagnetic field. At first, the electromagnetic compatibility is discussed. Basic terms are explained, followed by insisting on resources of possible distrurbing of implantable devices and standards dealing with this issue. Furthermore, short chapter about devices affecting function of implantable devices is introduced. It means devices which patients with implantable devices may meet in common life, as well as devices used in common life, also devices used jn medical environment. In the next part, measuring process of electromamagnetic effect in working compartment of FN Brno magnetotheraphy and elektrotheraphy is devised. There is a concept of measuring card thanks to which impulses of implantable devices are measured. Finally, a description of measuring on implantable devices in FN Brno. MIKULA, D. EMD instruments and electromagnetic immunity. Brno, 2009. 74 s. Master’s thesis in Brno University of technology on faculty of elektrical engeenerig and communication. Supervisor Ing. Marie Havlíková , Ph.D.

Meassurement PC rad based on I51 microcontroller
Klezla, Petr ; Kaňa, Zdeněk (referee) ; Bradáč, Zdeněk (advisor)
The main topic of the thesis is to suggest and realize the measuring card with analog inputs and outputs. In the first part of this thesis we are concerned with key-elements of measuring cards, respectively ADC and DAC, and here are explained all their activities. Then we attend of choosing parts for suggested measuring card as is voltage reference, power supply and operational amplifier. Among others we are concerned with a question of protecting inputs against overvoltage and reversing of polarity and beside against disturbance. Then follows analysis of used microcontroller ADUC831 with description of its used outskirts. Here is described the stored for measured samples of MMC memory, how to work with it and the programme service. The last chapter describes suggested firmware and servicing programme for PC. In fine we value the quality of measuring card and its mistakes.
