Syllabus
Course overview and goals
The main aim of this lecture is to make students understand fundamentals of physical layers of electronic communication systems. Especially, students are expected to learn principles of some modulation and demodulation schemes and to understand how these schemes are applied to real communication systems.
Course description and aims
At the end of this course, students will be able to:
1) regard channels as abstract mathematical models,
2) explain how modulation schemes transform baseband signals into bandpass signals,
3) explain how demodulation schemes derive baseband signals from bandpass signals.
Keywords
baseband signal, bandpass signal, amplitude modulation, frequency modulation, phase modulation, coherent detection, non-coherent detection, sampling theorem, digital modulation
Competencies
- Specialist skills
- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
Class flow
Students are provided with exercise problems about items explained in each class.

Study advice (preparation and review)
To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.
