ECO111 is an introductory course in Electrical Engineering, providing an introduction to simple electrical circuits as well as the technical skills to analyze such simple circuits. It is a course suitable for students pursuing further studies in electrical or telecommunications engineering as well as some other related engineering disciplines including computer engineering. In the practical section, it provides hands-on experience in building and testing circuits. It is packaged in such a way that students, having taken this course, can go away and build and analyze some practical, useful devices afterwards. It is a pre-requisite for the subsequent course on Circuits and Signals. 

ECO 222 is an main course in Electrical Engineering, providing an introduction to Maxwell equations, plane and circular waves travelling in various mediums as well as  the technical skills to analyze such physical quantities. It is a course suitable for students pursuing further studies in microwave engineering as well as some other related engineering disciplines including wave propagation and antennas design. In the practical section, it provides hands-on experience in building and testing RF and microwave circuits. It is a pre-requisite for the subsequent course "antenna engineering"
