This course introduces the basic analysis of analog and digital electronic circuits, as well as the basic principles of communication circuits. The analog circuit analysis includes: basic circuit laws and theorems; mesh and nodal analysis; resonant circuits, steady-state and small signal analyses; electrical amplifiers. The digital logic circuit analysis includes Boolean algebra; logic gates; combinational logic circuit and sequential logic circuit design; synchronous and asynchronous sequential machine design. Overview of the computer architecture will be introduced. Examples of common electronic circuits will be discussed as case studies.
