Course Description and Outcomes:
This is the third course in Electrical Circuit/Signals/Systems 3-course sequence. The student learning objectives are outlined below:
  • Understand the core concepts and applications of signal processing and linear system theory
  • Utilization of Fourier Analysis in both continuous and discrete time signals and systems
  • Role of sampling and the process of reconstructing a continuous-time signal from its samples. The processing of continuous-time signals that have been converted to discrete-time signals through sampling
  • Process of embedding an information-bearing signal into a second signal is typically referred to as modulation. Extracting the information-bearing signal as demodulation
  • Understanding of Laplace transform and Z-transform including their application to Signal and Systems
  • Mastery of using MATLAB solving Signal and Systems problems
  • Demonstrate the ability to work effectively in a team

  Final Project Demo and Report
  Comprehensive Final Exam - for schedule visit: www.clark.edu/academics/schedule


Student Evaluation:
  • End of chapter homework draft & review (20 points each)
  • Midterm tests (100 points each)
  • Comprehensive final exam (150 points)
  • Labs Planning, Execution and Reports (20 points/lab)
    Each student is expected to complete the weekly lab assignments during lab time. Even though some labs May be performed as a group, the report is to be completed individually, and due on the following lab period.
  • Final Project: Proposal, Design, Implementation, Report (50 points)
    Each student as part of team of 3 or fewer students is expected to define, implement and test a final project in accordance with the Final Project requirements. Each team will be responsible for demonstrating its solution and submitting a written Final Project Report.
    Note: In order to be eligible to receive a passing grade for the course, all labs and Final Project must be completed (including reports).


Timeliness:
Points are only awarded for tests, quizzes, labs and projects that are completed and delivered on the assigned due dates and times. In all other instances, zero points will be awarded unless the student has made prior arrangements with the instructor.

Course Letter Grade:
Final class letter grade will be awarded based on the total percent of possible points earned by each student as outlined below:

A A- B+ B B- C+ C D F
>94% 94-90% 89-87% 86-83% 82-80% 79-76% 75-70% 69-60% <60%


Conduct:
Students are required to read and follow the Student Responsibilities and Code of Student Conduct as outline in the institute's Catalog.

Cheating/Plagiarism: You are expected to do your own work. Copying or rewriting someone else's online or offline work, having someone else do your work, or cheating in any fashion will result in zero point for that test or assignment in addition to penalties prescribed by college policies. A second offense will result in an automatic 'F' for the class.

Computer or Equipment Misuse: Students are expected to obey the Equipment and Computer Usage Guidelines. Students who misuse the equipments or computers will be expelled from the class and/or lab.

Emergency Exception:
If the instructor judges that the situation warrants special consideration, he may choose to make special allowances in extreme cases.
