Course objectives
The course is a free continuation of the basics of semiconductor components in the course "Sensors and Measurement of Physical Quantities" and expands the topic of designing simple electronic circuits. In the next part, more complex analog and analog / digital electronic connections used by measuring and control systems are discussed.
