Electronic Circuits and Filters

Lecturer:

Jiří Hospodka (gar.), Pravoslav Martinek

Tutor:

Jiří Hospodka (gar.), Pravoslav Martinek

Supervisor:

Department of Circuit Theory

Synopsis:

Subject deepens and consolidates knowledge in the field of analog electronic circuits and frequency-selection filters. Analytical procedures are the gist that lead from complete models of analog integrated circuit structures, through the simplification, to a deeper understanding of their characteristic. Design fundamental is obtained by the analysis of the dominant influences to the circuit activities. Design and realizations of analog filters is introduced in the next part.

Study Objective:

Subject deepens and consolidates knowledge in the field of analog electronic circuits and frequency-selection filters. Analytical procedures are the gist that lead from complete models of analog integrated circuit structures, through the simplification, to a deeper understanding of their characteristic.

Credit is obtained on the basis of a semestral work. The final result is determined by the oral examination.
