Learning Objectives:
- Learn what radios actually do
- Learn about long distance communication systems
- Learn about the benefits of understanding radio and electronics
- Learn the difference between analog and digital radios
- Learn the difference between AM and FM
Understanding everything in Radio & Electronics is not the goal. Instead I want you to have an early start in electronics. Making electronic circuits and radios can lead to bigger discoveries and inventions.
There is a lesson list with learning objectives on the main course page. Print it out – along with your quizzes – and keep them for a record of what you learned in this section.
I hope you enjoy. I will include a survey on the final lesson. I appreciate your feedback.
