Assessment pattern

Alternative Assessment

It is not feasible to run an identical resit of the Continuous Assessment component during the Summer vacation. In view of this, if you fail the Continuous Assessment UoA you will be asked to complete an additional experiment during the Summer vacation. 

Assessment Strategy

The assessment strategy is designed to provide you with the opportunity to demonstrate and develop subject knowledge and understanding (exam and coursework). Thus, the summative assessment for this module consists of:

• 
  In-class Test (addresses learning outcomes 1–5);
  


• 
  Lab report  (addresses learning outcomes 1–5, 7, 9–15);
  


• 
  Electronics Design Problems (addresses learning outcomes 1–8);  and
  


• 
  Laboratory Continuous Assessment (addresses learning outcomes 9–14).
  

Formative Assessment:

Formative Assessment and feedback will be given to you in tutorials, throughout the laboratory sessions, during the in-class exercises, in the form of regular examples in lectures and engaging students in solving problems, providing instant feedback.  

Feedback

Verbal feedback will be provided in laboratory experiments. Written feedback will be given on the laboratory report and electronics design problems.

Module aims

• Introduce the fundamentals of electric circuit analysis and analogue electronics.
• Introduce the fundamentals of passive and active audio electronic devices.
• Introduce electronics laboratory equipment, circuit prototyping, and component-level troubleshooting.
• Introduce the fundamentals of circuit simulation and design.
• Introduce tools for technical writing, including typesetting and creating high-quality figures and plots.
• Encourage a technical awareness that will be of general use throughout your career in the audio industry.
• Promote collaborative coding practices, encouraging students to collaborate on projects to simulate industry-like teamwork.

Learning outcomes

Methods of Teaching / Learning

The learning and teaching strategy is designed to develop your skills and knowledge in analogue electronics and circuit analysis, in order to give you confidence with electronic circuits commonly found in audio equipment and to provide a foundation for audio circuit design in later modules.

The learning and teaching methods include:

• Lectures, including an in-class test


• Laboratory sessions


• Workshops on DC and AC circuit analysis


• Workshops on typesetting and report presentation


• In-class group and individual exercises


• Video resources and homework exercises via the course web page


• Coursework assignments and feedback

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
