Alternative Assessment

As this module involves Continuous Assessment, it is not feasible to run an identical resit of this aspect during the Summer vacation. In view of this, if you fail the Electronics coursework you will be asked to complete an additional experiment during the Summer vacation and write a lab report, which will be assessed.

Assessment Strategy

The assessment strategy is designed to provide you with the opportunity to demonstrate and develop your knowledge and understanding of electronics (Electronics Coursework and exam), and audio signal processing (Audio Signal Processing Coursework and exam).

Thus, the summative assessment for this module consists of:

•      Electronics Coursework – one written assignment answering practical problems, one lab report, and continuous assessment during labs (addresses learning outcomes 1-16).

•      Audio Signal Processing Coursework – two signal processing assignments consisting of mathematical problems (addresses learning outcomes 17-22).

•      2hr exam – Written paper given under exam conditions (addresses learning outcomes 1-13 & 17-21).

Formative  assessment

There are no formal formative assessment components for this module, but formative feedback will be given to you in tutorials and throughout the laboratory sessions, and in the form of regular revision questions in lectures.

Feedback

Verbal feedback will be provided in laboratory experiments. Written feedback will be given on the coursework  assignments.

Module aims

• To introduce the fundamentals of circuit analysis and analogue electronics.
• To encourage a technical awareness that will be of general use throughout your career.
• To build on previous mathematical knowledge and understanding to provide the relevant mathematical and signal processing background for modules in Acoustics, Electroacoustics, Sound Synthesis and Audio Engineering.

Overall student workload

Independent Study Hours: 87

Lecture Hours: 48

Laboratory Hours: 15

Methods of Teaching / Learning

The learning and teaching strategy is designed to: further develop skills and knowledge in

analogue electronics, circuit analysis, and signal processing, allowing modules in later years to

build on this knowledge.

The learning and teaching methods include:

• Two two-hour lectures per week

• Five three-hour laboratory sessions

• Guided reading

• 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.
