• Attendance
  • There will be no penalty at all until 1/4 unexcused absences of approx. 30 class meetings including those within the registration period.
  • But more than 1/4 unexcused absences will result in F without exception.
  • For excused absences, please provide the related documents and confirm that the electronic attendance system shows your attendance.
  • Remember that the system regards 2 late attendances as a single absence.
• Grading Policies for Homework and Quiz
  • Re-grade requests must be filed in writing within one week after graded quizzes have been returned to students.
• Grading Policies for Exam 
  • Re-grade requests must be filed in writing within one week after the graded exam has been returned to students.
• Final Grade

  • How to determine the final grade: https://youtu.be/XcCtY-25ybg?t=148
• Voluntary Project: 15-20 min. presentation on your report, MATLAB code, etc.
  • If you are about to fail in this course: https://youtu.be/XcCtY-25ybg?t=189
  • This is not applicable if your unexcused absences > 1/4 of class meetings.
• What I expect from you in this course:
  • How to study in POSTECH: https://youtu.be/ol9eLr2XAQI
  • Greek Letters: https://youtu.be/0mt0FOEzTzE
• Policy on Academic Dishonesty
  • If the instructor suspects academic dishonesty, the instructor will notify the student(s) and follow the procedure to report to the school without any exception.
  • Students have the responsibility to be knowledgeable about the consequences of dishonesty.
  • See, recently published report cover page and academic honesty guide.

• Pre-requisites: (For any pre-requisite related questions, consult the instructor.) 

Calculus, Linear Algebra, Differential Equations (or working knowledge on linear constant-coefficient differential equations)

• Course Objectives:

This course lays the groundwork for further studies in Communications, Signal Processing, Control, and related fields. By completing this course, students will gain an understanding of:
1. the concepts of signals and systems,
2. how to analyze linear time-invariant systems by using time-domain and frequency-domain approaches,
3. how to design linear time-invariant systems by using time-domain and frequency-domain approaches,
4. how to convert a continuous-time signal to a discrete-time signal, and vice versa.
