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 (test and coursework). Thus, the summative assessment for this module consists of:

• in-class test - a multiple-choice computer-based test on the fundamental subjects of electric circuit analysis (addresses learning outcomes 1-5);
• lab report - a technical report based on experimental results (addresses learning outcomes 1-5, 7, 9-15);
• electronics design problems - a series of circuit design problems completed in the form of an analytical design exercise, focusing on filter design, transistor amplifiers, and op-amp circuits (addresses learning outcomes 1-8);  and
• laboratory continuous assessment - a series of laboratory experiments involving circuit construction, testing, and measurement (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

• To introduce the fundamentals of electric circuit analysis and analogue electronics.
• To explain the fundamentals of passive and active audio electronic devices.
• To introduce the operation of semiconductors and active circuit design.
• To introduce the fundamentals of circuit simulation and design.
• To introduce electronics laboratory equipment, circuit prototyping, and component-level troubleshooting.
• To develop technical writing skills, including typesetting and creating high-quality figures and plots.
• To encourage a technical awareness that will be of general use throughout your career in the audio industry.
• To promote collaborative coding practices, encouraging you 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, used to introduce the theoretical elements of the module;
• laboratory sessions, to allow you to put the theory into practice;
• workshops on circuit analysis, and on typesetting and report presentation, to enable you to develop your skills in an interactive environment;
• in-class group and individual exercises, to enable to develop your skills with support;
• video resources and homework exercises via the course web page, to encourage you to engage more deeply with the topic;
• coursework assignments and feedback, to enable to consolidate and demonstrate your learning.

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.
