Communication Princi ...

Course Objectives: 
In this course, students must learn basic signal processing in order to understand modulation theory. This 
includes both CW and pulse modulation. At the end of the course, an introduction to noise calculation will be 
given. 
Course Prerequisite(s): 
The student must have taken a preliminary course on signals and systems 
Course Outline: 
● Introduction and Basic Terminology of Communication 
● Review of Signals and Systems: Classifications of signals, representation of signals using rotating 
phasors, Fourier series, Fourier transform, impulse function. 
● Linear Time Invariant Systems: Basic definitions, impulse response, transfer function, 
Distortionless transmission, Bandpass signals and bandpass systems 
● Introduction to Modulation: Classification of modulations according to carrier type 
- CW Modulation "Linear Modulation" (for both analog and digital messages): DSB AM, 
mixing, superheterodyne concept, spectrum analyzer; DSB SC, Carrier recovery problem, SSB, VSB, 
QAM (for digital communication) 
- CW modulation Exponential Modulation: Return to the definition of frequency and phase, FM and 
PM definitions, Relationships between the modulations, Narrowband PM and FM, Sinusoidal 
modulating waveform, Carson's rule, FM through LTI systems, FM through memorilessnon linear 
systems, FM production, FM demodulation: Slope demodulator and PLL demodulation 
● Pulse Modulation: The sampling theorem, PAM, PDM, PPM, PCM and quantization noise 
● Introduction to Noise Analysis in Electronic Systems: Thermal noise, shot noise, signal to noise 
ratio, noise figure 

Assessment Method: Continuous + Final Exam
