To transmit information practically, information is handled as a physical signal. To achieve this, students will understand
the basic theory of modulation and demodulation. Specifically, the analysis of signal waveforms in communication systems and
various analog and digital modulation and demodulation methods will be explained. Exercises will be conducted to help students
understand the lectures.
To understand the basic theory of modulation and demodulation, which is the foundation of information communication.
- You can explain the definitions and theorems of the concepts of signal analysis, waveform transmission, and amplitude, phase, and frequency modulation schemes.
- Through exercises, you will be able to solve problems in signal analysis, waveform transmission, and each modulation scheme.
- You can explain the basics of communication methods used in actual information and communication systems.
