  3. SYNOPSIS The aim of this subject is : to introduce the students with the basic principles and components of communications system. This subject will cover various topics such as: Introduction to Communication System, Analogue Modulation and Demodulation (e.g. Amplitude Modulation), Angle Modulation (Frequency Modulation and Phase Modulation), Digital Modulation, Noise in Communication System, Transmission System and Transmission Lines.

  4. COURSE OUTCOMES (OBE)

  5. REFERENCES Wayne Tomasi, “ Electronic Communication Systems Fundamentals Through Advanced” 5th Ed, Prentice Hall, 2004. Paul Young, “Electronics Communications Techniques”, 5th Edition, Prentice Hall, 2004. Mullet , “Basic Telecommunications:The Physical Layer”, Thomson Learning, 2003.

  6. ASSESSMENT Final Exam = 50 % Coursework = 50 % Test x 2 = 15 % Lab Session = 20 % Lab Test = 10% Assignments/Quizzes = 5%

  7. Signals and Systems Defined A signal is any physical phenomenon which conveys information Systems respond to signals and produce new signals Excitationsignals are applied at systeminputs and responsesignals are produced at systemoutputs

  8. A Communication System as a System Example A communication system has an information signal plus noise signals This is an example of a system that consists of an interconnection of smaller systems

  9. Signal Types

  10. Conversions Between Signal Types Sampling Quantizing Encoding

  11. Sound Recording System

  12. Recorded Sound as a Signal Example “s”“i” “gn” “al”
