Biological Signal Generator
Kadeřábek, Jan ; Čech, Petr (referee) ; Sekora, Jiří (advisor)
This semestral thesis describes signal EKG, it’s origin, evaluation and device for his generation. After identification with standard course of EKG signal, was such as signal created in program language Matlab. It’s consisting of 10 sinus courses, where each of them has it’s own frequence, start phase and amplitude. Each of this part of EKG signal is beat frequence variant. Rates of it’s durations and sizes were fixed from medicin literature. Such as created program were rewritten to program language C and is basic of main program, which control signal processor. Finally was propoused preparation, which will be generated this signal. Outcome of this thesis is teoretic treatise about signal EKG, created program for generation of this course include part control and machine doing realization of biological courses.

Identification of AC induction motor parameters
Křížek, Tomáš ; Václavek, Pavel (referee) ; Blaha, Petr (advisor)
This thesis describes and realizes (in program Matlab/Simulink and in the microcontroller Freescale 56F8346) one off-line identification method of AC Induction motor parameters which are necessary to implement the field-oriented control strategy. The identification metod identify leakage inductance, magnetizing inductance and secondary time constants. The presented method is evaluted, advantages and disadvantages of this method are evaluated with reference to their possible use in real-machine. The experimental results and schemes which are presented demonstrate the feasibility methods. The thesis is dividend in seven chapters. Second chapter describes the basic principle and model AC induction motor. Third chapter generally describes identification methods. Fourth, fifth and sixth chapters deal with method which is based on a previous work of the authors [4] and [5].

The automatic self tuning system for seven-string guitars
Jeřábek, Vojtěch ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
The thesis describes a realization of the automatic self tuning system for sevenstring guitars. There are comparisons of commercial and uncommercial solutions for six-string guitars. There is also evaluation of useful parts for seven-string guitars. Thesis contains a description of a requirements for individual parts and a control software with respect on real guitar properties and used computing algorithm. In the second part of thesis, there is a description of final system design and its realisation including the control software. This is also related with testing of the entire system.

Device for audio signal processing by means of signal processor
Lev, Lukáš ; Rumánek,, Jaroslav (referee) ; Brančík, Lubomír (advisor)
Master´s work discusses the issue of processing audio signal by means of signal processor. At present, the signal processor occurs in almost all devices that process or somehow modify sound in digital form. The aim of this master´s thesis is to study the signal processors from different producers, which are now on the market and select one suitable type for device that will process the audio signal. With this signal processor then propose a circuit diagram for a device that will process the audio signal and the PSpice simulation of the circuit and construct this device.
