Learning outcomes of the course unit: By completing the course the student will gain basic knowledge of the analysis of simple linear electrical circuits (EO) with stationary, sinusoidal and non-harmonic periodic circuit quantities (voltages and currents) in steady as well as in transient state. Based on the acquired knowledge, the student will be able to calculate circuit quantities for a particular circuit. The students will also get in touch with the circuits with distributed parameters and their use in cosmic engineering technology. Successful completion of the course is therefore an essential basis for understanding the subject matter, which is the content of subjects dealing with space communications.
