The Innovation of oscillators in mechanical-electrical keyboard instruments
Prokop, Šimon ; Buzzi, Mario (referee) ; Jirásek, Ondřej (advisor)
The bachelor thesis deals with innovations of oscillators of mechanical-electric keyboard instruments, especially from the perspective of frequency spectrum innovations. On the basis of the original oscillators of the Rhodes Mk 7 instrument, innovative virtual models of these oscillators were created in SolidWorks, which were subsequently analyzed in Ansys. Subsequently, these assemblies were physically fabricated and tested. In the final evaluation, the signal spectra of the upgraded assemblies were compared with the original tone and the analyzed data. The theoretical part of the thesis also discusses basic signal processing methods and describes methods for evaluating sound perception using psychological acoustics.

Technical Analysis
Mičánek, Filip ; Doubravský, Karel (referee) ; Novotná, Veronika (advisor)
This thesis deals with technical analysis, which is used to predict future development of stocks. The first part describes the theoretical background needed for the next section. This is followed by analysis of the current state, which assesses the current situation. The main part is devoted to the creation of a program to support technical analysis for the novice investor and the demonstration of its use in trading.

Preparation for function demonstration of basic types of oscillators
Venhoda, Jaroslav ; Šotner, Roman (referee) ; Brančík, Lubomír (advisor)
Bachelor's thesis deals with basic types of oscillators. Oscillators were divided into groups in the introduction. For the practical implementation was chosen four different types of oscillators. For each type of selected oscillator was done circuit design. Subsequently, the design was simulated by PC software OrCAD PSpice. The proposal includes a possibility of the control device by switching between outputs and tuning oscillator's frequency.

Behavioral Model of Current Conveyor with Advanced Controllable Inter-Terminal Relations
Jagla, Lukáš ; Langhammer, Lukáš (referee) ; Šotner, Roman (advisor)
Bachelor's thesis deals with model of current conveyor with advanced controllable inter-terminal relations. The behavioral model based on commercially available active devices has been proposed and designed as real implementation (including BCP design for experiments). Features of the behavioral model are verified by PSpice simulations as well as by experiments. Proposed device is utilized for synthesis and design of unconventional types of electronically controllable sine-wave oscillators and electronically adjustable filters. Simulated characteristics of the behavioral model as well as proposed applications are compared with experiments.
