Troubleshooting Electronics

Troubl1

This class is designed as a practical, industrial-applied session for electrical engineers and electronics technicians who would like to learn powerful, effective troubleshooting techniques of electronic circuits and systems, enabling them to continually enhance their troubleshooting skills and proficiency.

They will leave with a better understanding and an increased knowledge of the many valuable troubleshooting methods and best practices, as well as useful hints and tips that will help them to efficiently and successfully perform their work.

Lectures will be used to introduce new information and concepts. Simulations will be used to provide you with a safe and controlled environment to practice new skills or to explore different scenarios. Hands-on activities will allow you to apply what you have learned in a real-world context.

By combining these different learning methods, this will be a learning experience that is both engaging and effective.

We will discuss topics and answer questions such as:
