ELEC ENG 1100 - Analog Electronics

North Terrace Campus - Semester 1 - 2023

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.

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

In accordance with the Assessment for Coursework Programs Policy, Procedure 1b: An exemption from the stated hurdle requirements has been granted.

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 the exam, and at least 50% in the practical component. 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 replacement 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 replacement opportunities. However, if students persistently neglect the practical component throughout the 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 (maybe 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.

Assessment Detail

End of Topic Tests: Test 1 covers Topics 1 and 2; Test 2 covers Topics 3 and 4; and Test 3 covers Topics 5 & 6. The tests are held online in MyUni and are not invigilated. They are open-resource but students must complete the questions themselves.

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 student feedback from 2023:
* Marks for the tests are redeemable
* Slide presentations updated with key concept videos for foundation topics
* New open resource textbook
