Objective

The course is about basic circuit laws, theories and analysis techniques that are foundation of most courses of the electronic engineering curriculum. It is about analyzing how a circuit responds to a given input and how the interconnected elements in the circuit interact. The course starts with the introduction of basic circuit concepts and the properties of basic circuit elements, and then presents basic circuit laws, theorems, principles and analysis techniques. Dynamic (time-dependent) responses of circuits containing up to two energy-storage elements are then discussed, followed by the introduction of the important concepts of phasor and impedance and their application in AC circuit analysis. Finally, frequency responses of series and parallel resonance circuits are analyzed and their applications are discussed.

This course requires the students to have acquired knowledge on complex number and basic electromagnetism. The knowledge taught in this course is essential for students to take more advanced courses on circuit analysis and design, such as ELE2110 and ELE3210.
