ELEC ENG 1100 - Analog Electronics

North Terrace Campus - Semester 1 - 2021

This course develops a basic understanding of the fundamentals and principles of analog circuits and electronic devices in electrical and electronic engineering. This understanding is a critical step towards being able to design new electronic circuits or use them appropriately as part of a larger engineering system. Hence the course seeks to develop foundational concepts and skills, but does so through a series of application-oriented topics such as the design of DC power supplies, speed control of electric motors, and audio amplification and tone control. Learning opportunities include: online presentations with integrated practice exercises; tutorials in which small teams work together to explore, discuss, analyse and explain electronic circuits; and practicals in which theory is put to practical application. Important topics covered include: the key electrical variables and the application of fundamental circuit laws and theorems to DC and AC resistive circuits; power supply applications of diodes and switch-mode transistors; the operating principles of DC, induction and synchronous machines; analysis of simple operational and single-MOSET amplifiers; methods of systematic circuit analysis; and steady state sinusoidal analysis of RLC circuits. The course is designed to be one of the first undertaken by new students in electrical and electronic engineering such that successfully completing the course will provide the necessary foundation for more specialist learning in analog and radio frequency electronics and electrical power systems.

Online Learning

This course will use a variety of online resources to support the learning process. Recorded slide presentations on key concepts, theory and methods will be made available prior to scheduled lectures, at which the content of the presentations will be discussed in more detail, in the context of applications and problem-solving exercises. It is essential that student view the slide presentations or read the slides before attending lectures.

Video recordings of lectures will normally be made available on the course website after each lecture.

In addition, the following material will be provided on the course website at the start or during the course of the semester:
• slides, slide presentations, and tutorial questions
• some past assessment examples (tests and exams)
• additional practice questions

All course announcements will be made via the course website..

The use of the course discussion boards is strongly encouraged for questions relating to course material, but also for more general discussion on electrical and electronic engineering and technology. Anonymous posts will be permitted were possible, offensive posts will not. Lecturers will make a best effort to respond promptly to questions raised on the discussion boards.

The course gradebook will be used to return continuous assessment marks. Students should check the gradebook regularly and confirm their marks have been correctly entered.

Small Group Discovery Experience

There is no formal Small Group Discovery Experience identified in this course, but students will work in small groups under the guidance of academic staff, in the laboratories and in problem-solving tutorials.

The University's policy on Assessment for Coursework Programs is based on the following four principles:

Assessment must encourage and reinforce learning.
Assessment must enable robust and fair judgements about student performance.
Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
Assessment must maintain academic standards.

This assessment breakdown is registered as an exemption to the University's Assessment for Coursework Programs Policy. The exemption is related to the Procedures clause(s): 1. b. 3.

This course has a hurdle requirement. Meeting the specified hurdle criteria is a requirement for passing the course.

Assessment Related Requirements

A hurdle requirement is defined by the University's Assessment for Coursework Programs policy as "...an assessment task mandating a minimum level of performance as a condition of passing the course.

In the Analog Electronics course the examination and practical components are hurdle requirements. It is necessary to achieve at least 40% in each one of these components. If the exam hurdle requirement is not achieved, the total course mark will be limited to a maximum of 49. If the practical requirement is not met, the total course mark will be limited to a maximum of 44.

It is important to note there is NO supplementary assessment offered for the practical component after the end of Week 12. By arrangement with the Practical Coordinator, it will be possible throughout the semester for students who are falling significantly behind to have supplementary opportunities. However if students persistently neglect the practical component throughout semester they are likely to not meet the hurdle requirement and hence fail the course without further opportunity for redemption. Exceptions will be made in the case of verifiable medical or compassionate circumstances beyond the student’s control.

If a student fails to meet a hurdle requirement, and is assigned a total mark for the course in the range of 45-49, then the student is entitled to an offer of additional assessment of some type. The type of assessment is to be decided by the School Assessment Review Committee when determining final results. The student’s final total mark will be entered at no more than 49% and the offer of an additional assessment will be specified e.g. US01. Once the additional assessment has been completed, this mark will be included in the calculation of the total mark for the course and the better of the two results will apply. Note however that the maximum final result for a course in which a student has sat an additional assessment will be a “50 Pass”.

If a student is unable to meet a hurdle requirement related to an assessment piece (may be throughout semester or at semester’s end) due to medical or compassionate circumstances beyond their control, then the student is entitled to an offer of replacement assessment of some type. An interim result of RP will be entered for the student, and the student will be notified of the offer of a replacement assessment. Once the replacement assessment has been completed, the result of that assessment will be included in the calculation of the total mark for the course.

Student Feedback

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

The following changes have been made in response to sutudent feedback from 2019:
* Two hour active tutorials
* Lecture more focussed on core concepts
* At least one class active learning exercise per lecture
* Reduced practical load
* Slower presentation of key concepts at the start of the course

Fraud Awareness

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
