Communication Engineering 3 (U00444)

? Credit Points : 20 ? SCQF Level : 9 ? Acronym : EEL-3-ELCEN

Communications: This course studies both analogue and digital communications techniques. However, the main emphasis is on analogue radio communications since the topics of digital communication and communication networks can be studied in detail in the fourth year. The method of learning is mainly by studying examples of real communications systems and the theory of their operation. Hardware demonstrations are used to illustrate the operation of some systems. At the end of the course the student should have a good grasp of basic communication theory, and the reasons for using a particular modulation type or system architecture.

Satway: Satway is an exercise in analogue circuit design to realise the circuitry to display a television signal as a picture on a standard oscilloscope.
