ELN 234 Communication Systems

Lecture: 3 Lab: 3 Clinic: 0 Credits: 4
This course introduces the fundamentals of electronic communication systems. Topics include the frequency spectrum, electrical noise, modulation techniques, characteristics of transmitters and receivers, and digital communications. Upon completion, students should be able to interpret analog and digital communication circuit diagrams, analyze transmitter and receiver circuits, and use appropriate communication test equipment.

Pre-requisite(s): ELC 131.  
Course is typically offered in Fall.
Course has transfer restrictions - 20 years

Student Learning Outcomes (SLOs)
At completion of the course, the student should be able to do the following:

  1. Explain the relationship among information, bandwidth, and time of transmission in a lab report.
  2. Draw an AM waveform with various modulation indexes without the use of a textbook or other reference.
  3. Analyze various power, voltage, and current calculations in AM systems in a lab setting.
  4. Differentiate between sensitivity and selectivity of a radio receiver in an oral report.
  5. Analyze the operation of a complete AM receiver system in a lab setting.
  6. Adapt an AM generator to provide SSB in a lab setting.
  7. Design a complete block diagram for an SSB transmitter/receiver in a lab report.
  8. Defend the multiplexing technique used to add stereo to the standard FM broadcast systems in a lab report.
