Unit 2: Introduction to Electronics (20%)

The purpose of this unit is to provide students with an opportunity to build knowledge and skills in analog and digital electronics. Students will use the theory of electronics to manipulate a variety of electronic components. They will learn how to plan design and fabricate circuits and subsequently use standard test equipment to explain the logic of the circuit and troubleshoot any problems that may exist. The skills learned in this unit will be used extensively when students begin the major design project in unit 5.
