Learning outcomes
|
The subject deals with passive and active elements of electronics from a functional, not a technology point of view. Principles of basic functional blocks are decribed. Laboratory practice supports the lectures by wiring and mesuring of selected components and simple circuits with an emphasis on self- dependent wiring of real elements on a connection module similar to a practical development of functional samples.
Students will acquire the basic concepts and practice skills of the electronic componets and basic analog functional blocks.
