This course provides the foundations for the study in Communications, Signal Processing, Control, etc.

Through this course, students will learn
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, and

5.( how to use MATLAB to perform digital signal processing.)

A two-page crib sheet of A4 size is allowed in each exam.
Only one or two problems of each homework will be randomly selected and graded.

Re-grade requests must be filed in writing within one week after graded quizzes have been returned to students.

1. In special cases, students may take exams earlier than the original schedule if he/she requests at least one week earlier. 
2. Excused class absence on an exam day may lead to a make-up exam for the absentee.
3. Re-grade requests must be filed in writing within one week after the graded exam has been returned to students.

Final grade will be given based on multi-facet assessment of the course requirements.

You will use the PRS system through this course. Once the PRS transmitter is distributed in the beginning of the semester, it's your responsibility to bring it at every meeting with fully charged batteries and return it at the end of the semester.

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.
