Examination methods

Written and oral exam.

Course assessment

Conducting university questionnaires on teachers (student-teacher relationship, transparency of assessment criteria, motivation for teaching, teaching clarity, etc.). Conducting Faculty surveys on courses (upon passing the exam, student self-assessment of the adopted learning outcomes and student workload in relation to the number of ECTS credits allocated to activities and courses as a whole).

Overview of course assesment

Learning outcomes
Upon successful completion of the course, students will be able to:

1. compare the spectra of periodic and nonperiodic (random) signals and calculate the power spectral density of a random pulse sequence

2. measure a modulated signal spectrum by spectral analyser and evaluate the measurement results

3. analyse the characteristics of modulation techniques: AM, FM, PSK, QAM and FSK, and compare them with respect to robustness to noise and spectral efficiency

4. calculate the parameters of a coaxial cable and two-wire cable, and compare the cables according to their transmission characteristics

5. explain the principle of electromagnetic wave generation as well as wave equations

6. compare antennas according to their parameters and choose an appropriate antenna in a radio system design

7. define parameters of a point-to-point radio link
