Anotace

The course is a proper continuation of the EC 1, with the methods of circuit analysis in periodic inharmonic steady state, solution of transient phenomena in the electrical circuits in time and frequency domain. Then characteristic equation, criteria stability and oscillation conditions are discussed. Principles of feedback systems, of analogue and digital filters, of circuit synthesis and of transmission lines are given. In conclusion solutions of nonlinear circuits are taught.

Sylabus
