The use of impulse sources necessitated the introduction of non-harmonic circuit solutions and transient solutions. Furthermore, the issue of two-ports and the basics of electrical filters is discussed. Linearized and linear circuits are a special case of nonlinear circuits that are presented in conclusion. 1. Advanced circuit solving methods - generalized nodal voltage method 2. Modified nodal voltage method, forbidden line method. 3. Signal Flow Graph Method - MC graph, short graph, Mason's rule for graph transfer 4. Circuits in non-harmonic steady state - Fourier series, determination of Fourier coefficients, determination of an, determination of bn, Fourier integral, Fourier transform, deformation power 5. Solution of transient processes - solution of differential equation 6. Solution of transient processes by Laplace transform, definition of Laplace transform, dictionary Laplace transform, Laplace images of basic elements, back Laplace transform 7. Two-ports - transfer characteristics of two-ports, matrix characteristics of two-ports, joining of two-ports, conversion of parameters, basic two-ports 8. Electric filters - types of filters, transmission characteristics of filters 9. LC filters 10. Active RC filters 11. Digital filters 12. Nonlinear circuits - graphical-calculation solution, numerical methods of solution - Newton's method, 13. Newton-Raphsns method, harmonic signal effect on nonlinear element

Learning outcomes
|
The course provides students with an idea of solving circuits in non-harmonic steady state, transient processes by integration of differential equations and Laplace transforms, electric filters and nonlinear circuits solutions.
After the study of this subject the student will have more deep knowledge of the fundamentals of electricity. Namely the student will be able to solve electric circuits with general form voltage and current sources, will have a basic knowledge about two-ports, filters, etc
