Details for undergraduate courses
• Level 3 core unit in the Electrical specialisation in the Engineering Science major sequence
• Category B broadening unit for Bachelor of Arts, Bachelor of Commerce and Bachelor of Design students
Content This unit introduces the fundamental circuit theory laws, abstractions, theorems, modelling and analysis techniques used in electrical engineering, and applies these problem solving techniques to the design and analysis of electrical and electronic systems. Topics include lumped circuit models for passive and active elements; Kirchhoff's laws, superposition; Thevenin/Norton equivalents, Bisection Theorem, Miller Effect, ordinary differential equations, time domain analysis of first and second order circuits with RLC elements; Laplace transform in the analysis of circuits, s domain characteristics of lumped elements, application of Kirchhoff's laws in s domain; systematic nodal and mesh analysis techniques; Poles and zeros of network functions; frequency and impedance scaling; two-port networks, matrix description of two ports; complex power maximum power transfer; device modelling; small and large signal analysis of analog/digital circuits; principles of amplifier design; basic amplifier stages and biasing circuits; static and dynamic behaviour of amplifier circuits including frequency response, feedback and stability, slew-rate and clipping; operational amplifier circuits. Emphasis is placed on software tools for circuit simulation and practical applications of the above concepts in the laboratory.
Outcomes Students are able to (1) formulate the fundamental circuit theory abstractions and principles on which the design of electrical and electronic systems is based; (2) model and analyse the behaviour of electrical and electronic systems, in both the time and frequency domain; (3) employ amplifiers circuits to process analog signals; (4) use software tools to analyse and design electrical and electronic circuits; (5) build passive and active electrical networks, measure circuit variables and explain discrepancies with mathematical models; and (6) work effectively as part of a team and communicate results in a concise technical report.
Assessment Typically this unit is assessed in the following ways: (1) laboratory reports; (2) class tests and quizzes; and (3) a final examination. Further information is available in the unit outline.

Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 overall and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.
Unit rules
 Prerequisites: completion of 18 points of the Level 1 and Level 2 units taken from the degree-specific Engineering Science major, including ENSC2001 Motion and ENSC2002 Energy and (MATH1002 Mathematical Methods 2 or MATH1011 Multivariable Calculus) Incompatibility: ENSC3017 Circuits and Electronics; ELEC2300 Circuits and Electronic Systems 2

• The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
• All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
• Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available at the University Co-operative Bookshop (from early January) and appropriate administrative offices for students to consult. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
