NELINEARNA KOLA

Passing the exam in this subject implies that the student can: - Distinguish the concept linearity and nonlinearity, define nonlinear element and nonlinear circuit; - Determine the v-i characteristic of a nonlinear resistive circuit and analyze it using one of the methods (analytical, graphical, piecewise-linear approximation); - Perform synthesis of desired characteristics using concave and convex resistors; - Determine the dynamic response and analyze the first-order piecewise-linear circuit; - Formulate nonlinear state equations describing a second-order nonlinear circuit and qualitatively describe their behavior using the concept of equilibrium states, trajectories, and phase portraits; - Analyze the behavior of nonlinear oscillators and explain the phenomenon of the jump; - Simulate the operation of nonlinear circuits on computers, critically evaluate the obtained results, and present them.
