Communication Technology
Waves, Sound & Light

Unit IV

Communications Technology Overall Expectations
By the end of this course, students will:

demonstrate an understanding of the scientific principles and technological applications involved in the design, development, and operation of communications systems;
design and carry out experiments to investigate and illustrate the fundamental operating principles and basic components of communications systems;
identify and describe Canadian contributions to communications technology, and demonstrate awareness of the wide-ranging and ever-growing influence of communications technology on the global community.

Wave motion and its ability to transfer energy is a key componenet of this unit. The emphasis in this unit is waves both light and sound.
