doc. dr. Andrej Hrovat


The aim of the course is to familiarize the student with the knowledge in the field of telecommunication systems.
The competencies of the students completing this course successfully will include
the ability to analyse, synthesize and anticipate solutions and consequences, to gain the mastery over research methods, procedures and processes and a development of the critical judgment.
