·       Understand noise, bandwidth, and link analysis.


Textbook:  “Digital and Analog Communication Systems”, 7th Edition, L. Couch, Prentice Hall, 2007, ISBN-13: 9780131424920.


Course Slides: We will go through the course slides in the class available at              (see below)

I urge you to download and review the slides before each class.  You are required to read the textbook after each class for further reinforcement.


Lab Instructions:  Please got to


Attendance: Attendance is mandatory.  There will be no excused absences except in the case of emergencies that could be substantiated.


Class Participation:  Your participation in the class and in discussions is valued.  Read the slides before you come to class and  develop questions to raise in the class


Homework:  Homework (see the list below) will be assigned periodically.  Submit your assignment in hard copy at the beginning of the due session.  Late submission will not be accepted and will receive zero. You must use MS Office (Word, Excel, PowerPoint), or text.  Hand-written solutions are not accepted.  Be neat, and organized.  There will be points for your presentation.

                Solving problems in this course is essential.   You can use the Student Solution Manual available at or to practice extra problem solving


Exams:  A mid-term and a final exam.  Exams are not optional.  You will receive zero if you do not appear for and exam.


Grading:  The course grades will be based on the following:

·      Homework assignments             30%

·      Midterm                                        15%

·      Final exam                                    30%

·      Lab                                                 25%


Academic Honesty:  You are responsible to behave ethically & honestly.  Copying, cheating, forgery, and other unethical or dishonest actions are not tolerated.  See


My Expectations:

·         Arrive on time to attend the class.  Unexcused absences will affect your grade.

·         Turn off cell phones, earphones and other distracting devices.

·         Preview the slides before each lecture and after the lecture.

·         Be responsible for materials covered in every class.

·         Hand in your assignments on time at the beginning of the class.

·         Speak up whenever you have suggestions or questions.


Learning Outcome:

·         Ability to apply knowledge of mathematics, science and technology principles to understand technological systems plus a broad understanding of the common terminologies and basic concepts used in analog and digital communications.

·         Ability to use computational methods, skills, computers, and current technical tools in practice.

·         Ability to analyze systems and conduct experiments.

·         Ability to analyze and interpret data to solve technical problems.


Tentative Schedule: Syllabus of each Chapter to be Covered, Homework Assignments and Due Dates. HW problems are from end of the chapters in the textbook unless indicated differently.  The Lab instructor will provide the syllabus for the lab sessions.
