Prerequisites by Topic
Lecture Topics:
  • Circuit elements and voltage node analysis
  • Transients in RL and RC circuits
  • Sinusoidal response in RL and RC circuits
  • Diodes and diode applications
  • Operational amplifiers: golden rules; typical op-amp circuits; departures from ideal op-amp behavior
  • Transistors: simple transistor model and typical applications
Class Schedule:

Meets for 3 hours of lecture and 2 hours of laboratory each week for 10 weeks.

Computer Usage:

LabVIEW and Excel are used in the laboratory

Laboratory Projects:

Students work in groups of 2 to 3 but write lab reports individually. There are four laboratory projects (3 hours each).

  • Lab1. Logging of data using a data acquisition card. Half wave rectifier and band pass filter circuits.
  • Lab2. Real time and logged data acquisition. Basic operational amplifier circuits, including the non inverting amplifier, inverting amplifier, and voltage follower circuits. Tracking the output of an operational amplifier in an open-loop configuration.
  • Lab3. Operational amplifiers and departure from ideal behavior: input bias current, input voltage offset, and frequency dependency of op-amp gain. The peak detector circuit.
  • Lab4. A power booster circuit using a transistor inside the feedback loop of an op-amp. In second part of the lab the students are asked to design, build and demonstrate a circuit for a given application
Professional Component

Contributes toward the Engineering Topics and/or Design experience for both Mechanical and Aerospace Engineering majors.

Design Content Description

Typically a design spec is given and a circuit is synthesized, constructed, and tested to the spec, or a given circuit is analyzed, constructed, and evaluated. Fifty percent of all grading in the class is related to design.
