Understanding of basic linear circuit constants and variables.
Course Objectives:
This course provides the foundational education in analog and
digital communication system analysis and design. Through lecture and
out-of-class assignments, students are provided learning experiences that
enable them to:
- Analyze and design basic communications systems, particularly with
application to noise-free analog and digital communications.
- Apply concepts and techniques from Fourier analysis and circuit analysis
to communication systems.
- Develop the ability to compare and contrast the strengths and weaknesses
of various communication systems.
Topics:
- INTRODUCTION (1 lecture)
Communication systems; analog and digital
messages; signal-to-noise ratio, the channel bandwidth, and the rate of
communication; modulation.
- REVIEW OF SIGNALS (1 lecture)
Size of a signal; classification of
signals; some useful signal operations; unit impulse function; signals and
vectors; signal comparison: correlation; signal representation by orthogonal
signal set; trigonometric Fourier series; exponential Fourier
series.
- REVIEW OF FOURIER ANALYSIS (1 lecture)
Aperiodic signal
representation by Fourier integral; transforms of some useful functions;
some properties of the Fourier transform; signal transmission through a
linear system; ideal and practical filters; signal distortion over a
communication channel; signal energy and energy spectral density; signal
power and power spectral density; numerical computation of the Fourier
transform: the DFT.
- AMPLITUDE (LINEAR) MODULATION (6 lectures)
Baseband and carrier
communication; amplitude modulation: double standard (DSB); amplitude
modulation (AM); quadrature amplitude modulation (QAM); amplitude
modulation: single sideband (SSB); amplitude modulation: vestigial sideband
(VSB); carrier acquisition; superheterodyne AM receiver.
- ANGLE (EXPONENTIAL) MODULATION (6 lectures)
Concept of instantaneous
frequency; bandwidth of angle-modulated wave; generation of FM waves;
demodulation of FM; FM receiver.

communication system; line coding; pulse shaping; M-ary communication;
digital carrier systems; digital multiplexing.
- SOME RECENT DEVELOPMENTS AND MISCELLANEOUS TOPICS (3 lectures)
Class Schedule:
Two 75-minute lectures per week.
Computer Usage:
Matlab and Simulink are used to facilitate analysis of
communication systems in lecture.
Laboratory projects and/or assignements:
None.
Contribution to meeting the professional component:
This course provides an analysis and design emphasis in the area
of communications systems. It is a prerequisite to the senior elective course
on communication system performance analysis in the presence of noise (EE
460). Topics pertaining to economics and manufacturability are considered in
the context of communication system circuit design and construction.
Relationship to program outcomes:
The course relates to the following program outcomes:
- Graduates will understand how to analyze and design basic communication
systems. [Ref: Outcome O.3.1.]
- Graduates will understand how to apply Fourier and circuit analysis and
design to basic communication systems. [Ref: Outcome O.3.2.]
