### 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.

Qualifying  condition(s):

This module is core and will require you to pass every unit of assessment with a mark of at least 40%.

### Module Overview

This module will introduce you to circuit theory, analogue electronics, and audio signal processing using a combination of theory and application, to give you the background needed for a wide range of the technical modules in each year of the Tonmeister programme.

### Prerequisites/Co-requisites

• None for Tonmeister students.

### Module Aims

This module aims to:
introduce the fundamentals of circuit analysis and analogue electronics.
encourage a technical awareness that will be of general use throughout your career.
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.

### 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
• Coursework assignments and feedback

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.
