PHY315: Electronics



Learning Outcomes
At the end of the course, students will be able to:
1. describe behaviours of semiconductors and their significance in the development of
modern electronics;
2. explain the operation of semiconductor devices and their advantages over their vacuum tube
counter parts; and
3. demonstrate the significance of modulation in telecommunication.
