"This course introduces fundamental concepts of communication systems and communications networks, including baseband signals, communication channel and noise, analogue modulation/demodulation, sampling and digitisation, digital modulation, and digital demodulation. Examples will be provided to support student learning. The course will include 16 teaching hours, covering lectures and examples. Three assignments will be graded. On successfully completing the course, students will be able to know about digital communications, understand the effect of channel and noise, and apply different modulation and demodulation techniques for communications."
