This course focuses on the signal transmission systems. Topics include the principle of signal systems, the transmission of pulse signals, frequency transform, modulation and demodulation, the applications of the signal transmission systems. By combining lectures and exercises, the course enables students to understand and acquire the fundamentals of designing linear systems, actual phenomena in the communication systems and designing method applicable to them, the modulation and demodulation for digital transmission system, and how they are used in the practical systems.
The digital transmission system covered in this course is widely used as the basis of the communication systems. Students will learn how information is converted to a signal and delivered to people through a transmission line.
By the end of this course, students will be able to:
1) Understand and explain the fundamental configuration of digital transmission systems.
2) Understand and explain the physical phenomena and its effects for communication systems.
3) Understand and explain the designing method of practical communication systems.
4) Consider the characteristics of designed system by solving or computing equations.
Corresponding educational goals are:
(1) Specialist skills Fundamental specialist skills
(4) Applied skills (inquisitive thinking and/or problem-finding skills) Organization and analysis
(7) Skills acquiring a wide range of expertise, and expanding it into more advanced and other specialized areas
