Why take this course?

This course is designed as an introductory course to the fundamental principles of electrical engineering for students not majoring in electrical or computer engineering. The course stresses breadth over depth, and introduces analysis techniques that cover basic electronic circuit elements, amplifiers and antenna systems. Having completed this course, the student should have sufficient background to successfully communicate with electrical engineers in modern engineering design team settings. In addition, completing this course successfully will provide the students the knowledge required to continue in more advanced courses dealing with electronics, controls, and instrumentation.

Learning Objectives

  • 1. Analyze the steady state response of electric circuits with R, L, and C components;
  • 2. Analyze circuits involving operational amplifiers and transistors, and obtain the transfer function for circuits containing filters and amplifiers;
  • 3. Use Boolean algebra to understand combinatorial and sequential logic circuits;
  • 4. Describe and apply the fundamental principles of Maxwell's electromagnetism equations to formulate radiation equations;
  • 5. Describe the performance of simple antenna systems, and perform basic link-budget analysis.
