The third and final online Circuits and Electronics courses is taken by all MITElectrical Engineering and Computer Science (EECS) majors.

Topics covered include: dynamics of capacitor, inductor and resistor networks; design in the time and frequency domains; op-amps, and analog and digital circuits and applications. Design and lab exercises are also significant components of the course.
Weekly coursework includes interactive video sequences, readings from the textbook, homework, online laboratories, and optional tutorials. The course will also have a final exam.
This is a self-paced course, so there are no weekly deadlines. However, all assignments are due when the course ends.
This course is part of the Circuits and Electronics XSeries Program.

What you'll learn:

  • How to construct and analyze filters using capacitors and inductors.
  • How to use intuition to describe the approximate time and frequency behavior of second-order circuits containing energy storage elements (capacitors and inductors).
  • The relationship between the mathematical representation of first-order circuit behavior and corresponding real-life effects.
  • Circuits applications using op-amps.
  • Measurement of circuit variables using tools such as virtual oscilloscopes, virtual multimeters, and virtual signal generators.
  • How to compare the measurements with the behavior predicted by mathematical models and explain the discrepancies.

Engineering Sci: Physics

The primary goal of the course is to enable the student to understand what semiconductors are, and why they are important to the electronics industry. Students will first learn and understand why some materials are insulators and others are conductors, and will learn how these properties can be modified. The course also explores other situations where the conductivity of an insulator can be drastically changed, such as the situation inside a bolt of lightning or inside a semiconductor.
