ET 289 - Electrical Troubleshooting
Credits: 1-4
Description
Maintenance and service of electronic equipment and troubleshooting techniques using electrical measuring and test devices. This course is designed for students who have completed electronics courses that cover DC-AC electronics, semiconductor devices, and digital electronics or have at least 2 years of experience in electronics.
Student Learning Outcomes
- Troubleshoot and repair unregulated half-wave, full-wave, double/tripler and bridge rectifier and power supply circuits.
- Explain testing and troubleshooting DC and AC bias points, frequency response, bode plots, gain vs. phase measurements, single and multistage amplifier circuits using bi-polar transistors.
- Build complementary symmetry circuits, push-pull circuits and measure the crossover distortion.
- Explain testing and troubleshooting transformer-coupled amplifier circuits, tuned circuits, Q vs. bandwidth, and frequency response of tuned circuits.
- Test and troubleshoot various operational amplifier circuit configurations, CMRR, input bias currents and offset voltage, slew rate limiting aspects of operational amplifiers.
- Explain integrated circuit voltage regulator measurements, line and load regulation.
- Explain characteristics of digital circuits, fan out, noise margin, open and short circuits and logic circuits.
- Explain the testing and measurement of optical and temperature sensors.
