Network Functions and Frequency Response: network functions of one- and two-port networks; network functions and sinusoidal steady-state response; Frequency response of linear circuits and network function design Lectures and tutorials are the primary means of conveying the basic concepts and theories of circuits and linear systems. Practical applications are given through several experiments to supplement the concepts discussed in lectures. Laboratory preparations are introduced to encourage extra-readings on relevant materials. √ √ 100 % The intended outcomes regarding the acquisition of the new concepts in circuit designs will be assessed by the usual means of homework, test and examination while the application of those concepts in practice will be assessed through laboratory experiments. The team work and communication skills will also be assessed by the laboratory experiments. Student Study Effort Expected Class contact: Lecture/Tutorial 42 Hrs. Laboratory 12 Hrs.
