The course cannot be taken simultaneously with:
Electrical Circuits 2B (X31EO2B)
Lecturer:
Ivan Zemánek (gar.), Václav Havlíček
Tutor:
Ivan Zemánek (gar.), Václav Havlíček
Supervisor:
Department of Circuit Theory
Synopsis:

The subject represents the continuation of EO1. It explains the difference

between time domain and frequency domain circuit analysis, defines the signal transformation concept, frequency spectrum, operational analysis (Fourier series, Fourier and Laplace transform). The subject is devoted to the periodic non-sinusoidal steady state linear circuit analysis and to the linear circuit transient analysis (both time domain analysis and operational analysis). The transient responses (unit impulse response, unit step response) and frequency responses of linear circuits are defined, their meaning, application and relationships are presented.

The subject is closed by the transient analysis of transmission lines.

Requirements:

The exam can be passed with credit only. It is necessary to attend 50 %

of exercises at least.
