Campus: Camperdown/Darlington
Pre-Requisites: ELEC2103 AND ELEC2104.
Brief Handbook Description: This unit of study is to build on the platform provided by the basic theory and technical units such as ELEC2104 Electronic Devices and Basic Circuits and ELEC2103 Simulation and Numerical Solutions in Engineering. Based on deep understanding of aspects in active analog filter design students are equipped with the knowledge and skills to design, and to be in a good position to undertake further self study as required.

This unit of study is conducted with theoretical study and design project practice. It covers the theory and design of active and passive analog filters including the followings: Fundamental concepts in circuit theory: network functions, characteristic frequencies; Types of filter: lowpass, bandpass, etc; Review of operational amplifiers; Design of first and second order filters using operational amplifiers; Cascade design; Typical filters: Butterworth, Chebyshev, etc; Frequency transformations in design; Sensitivity, etc.
Assumed Knowledge: 1. ELEC2401 Introductory Electronics or ELEC2104 Electronic Devices and Basic Circuits and ELEC2301 Signals and Systems or ELEC2302 Signals and Systems. 2. A knowledge of, and ability to use, complex numbers is essential, as are a familiarity with elementary circuit theory and basic concepts from linear systems theory. 3. Some understanding of the Laplace transform, and of polynomials and rational functions, is desirable, although knowledge of these topics is not required in great depth. 4. Some of these topics will be reviewed as necessary. It is assumed that students have some familiarity with MATLAB and or Spice.

Attributes listed here represent the key course goals (see Course Map tab) designated for this unit. The list below describes how these attributes are developed through practice in the unit. See Learning Outcomes and Assessment tabs for details of how these attributes are assessed.

Attribute Development Method Attribute Developed
In the design project students are put into a situation as in practice. A design goal is set but not particular techniques or pathways specified. Students are asking to design the product and to convince others that he/she has got a solution to the problem. Design and Problem Solving Skills (Level 4)
Wide range of knowledge in analog filter design is obtained and platform for further study and research is built. Discipline Specific Expertise (Level 5)
Fundamental theory in circuit design is introduced and practiced through tutorials and design project. Fundamentals of Science and Engineering (Level 3)
In tutorial and especially the design project the students will need to communicate with peers and demonstrate his/her design to others. Professional Communication (Level 2)
In the design project students are put into a situation as in practice. A design goal is set but not particular techniques or pathways specified. Students are asking to design the product and to convince others that he/she has got a solution to the problem. Professional Values, Judgement and Conduct (Level 2)
This course consists of 9 tutorials and a major design project. Teamwork work is encouraged though individual design required. Teamwork and Project Management (Level 2)

For explanation of attributes and levels see Engineering/IT Graduate Attribute Matrix 2009.
