ELEC ENG 1102 - Digital Electronics

North Terrace Campus - Semester 2 - 2024

This course provides an introduction to the control of engineering systems using microprocessors, sensors and actuators. Within this context it introduces the fundamentals of combinational logic, Boolean algebra, digital arithmetic, sequential logic, and microprocessor instruction set architecture and I/O. Learning opportunities include: online presentations with integrated practice exercises; tutorials in which small teams work together to explore, discuss, analyse and explain digital electronic circuits; and practicals in which theory is put to useful application. The course is designed to be one of the first undertaken by new students in electrical and electronic engineering such that its successful completion will provide the necessary foundation for more specialist learning in digital microelectronics and computer engineering.

  • Assessment

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

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. 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. a. i    1. b. 3.   
    This course has a hurdle requirement. Meeting the specified hurdle criteria is a requirement for passing the course.
    Formative means that the assessment is primarily for the purpose of developing understanding and obtaining feedback for improvement. Summative means that the assessments tests your understanding.
    Assessment Related Requirements
    The practicals are a hurdle requirement. It is necessary to achieve at least 40% in this components. If the hurdle requirement is not achieved, the total course mark will be limited to a maximum of 49.

    It is important to note that no modified arrangements for assessment are offered for the practicals after the end of Week 12. By arrangement with the practical or course coordinator, it will be possible throughout the semester for students who are falling significantly behind to have modified arrangements. However if students persistently neglect the practical 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 (normally no less than 40%), 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.

  • 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.

  • Student Support
  • Policies & Guidelines
  • 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.
