EL 250 - Electronic Communications

Credit Hours: 3

This course is an introductory study of analog and digital communications theory, systems, and circuits. Analog topics include modulation techniques, noise, tuned circuits, oscillators, AM, FM, and SSB modulation and demodulation, mixers, transmission lines, wave propagation, antennas, and microwave applications. The digital communications circuits and systems considered include PCM, television, and mobile telephone.

Course Outcomes
At the completion of this course, the student should be able to:

  • identify and describe a variety of modulation methods including AM, FM, SSB, PCM and QAM;
  • analyze communications circuits including RF, IF, and audio amplifiers, oscillators, detectors, AGC circuits, tuned circuits, filters, mixers, modulators, superheterodyne receivers;
  • identify transmission lines and describe the characteristics of each type;
  • describe the propagation of DC waves and standing waves in transmission lines;
  • describe electromagnetic waves, their properties and behavior; and
  • explain the effects of modern communications methods on society.
