Abstract

The thesis is concerned with the qualities of transfer function in phase two-port circuits. It offers a detailed description of first order active phase two-port circuits. The following part focuses on basic description of oscillators and the conditions for emergence of oscillations. The thesis presents schemes and computations of particular variables of individual connections of phase two-port circuits. In the practical part of the thesis, the designed multiphase sinusoidal oscillators (2, 3, and 4-phase) are used to do measurements in the laboratory and a simulation in NI Multisim program. The conclusion of the thesis offers a comparison of the variables simulated in NI Multisim program and the measured values in the laboratory with my own computed values.
