The objective of the subject is to inform students about potential of electronic circuit simulations. The course is based on concrete applications. Themes of the first part of the lectures are put to a test on basic circuits. Specific circuit applications follow with a detailed explanation and a simulation in exercises afterwards. Selected circuits will be checked by laboratory measurements.
Basic knowledge of electrical and electronic circuits and their analysis.
The course aims to introduce students to the possibilities of electronic circuit simulation and practical measurement of their parameters in laboratory exercises.
Credit is obtained by processing semestral tasks (simulation and measurement). The overall rating is based on the score during the semester and the oral examination.
