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.

Theremin
Musil, Petr ; Olejár, Adam (referee) ; Vlček, Lukáš (advisor)
This bachelor thesis focuses on the construction of the musical instrument theremin. Theoretical section of this thesis describes various types of oscillator and its potential use in construction of the musical instrument. Practical section of this thesis deals with specific circuit design, its simulation and construction of pitch control circuit, volume control circuit, mixer, preamplifier and supply voltage regulator. Principle of operation is based on mixing two high frequency signals produced by Colpitts oscillators.
