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.
This module is core and will require you to pass every unit of assessment with a mark of at least 40%.
This module is intended to advance your understanding of circuit theory, analogue electronics, and audio signal processing using a combination of theory and application. This should give you the background needed for a wide range of the technical modules in each year of the Tonmeister programme.
• Year 1 Electronics and Audio Signal Processing A.
• To introduce the fundamentals of electronic devices and amplifiers.
• To introduce important skills such as component level troubleshooting.
• To continue to give you the necessary signal processing background for audio engineering.
On successful completion of this module, you should be able to:
1. explain the theory of operation of semiconductor devices (C, K)
2. describe the characteristics of ideal and real diodes (including zener diodes) (C, K)
3. analyse the operation of simple power supply circuits, and specify components for a given performance (C, K, P)
4. design and analyse simple transistor amplifiers and op-amp amplifiers (C, K, P)
5. use an audio test system to measure basic audio system parameters such as signal-to –noise ratio and THD+N (C, K, P)
6. use basic fault finding and troubleshooting methods to identify common audio equipment faults (C, K, P)
7. predict the behaviour of a circuit through the study of circuit diagrams (C, K, T, P)
8. perform convolution on two signals in both the time and frequency domains (C, K, P)
9. calculate the impulse response and transfer function of linear time invariant systems (including comb filters) and plot the phase and magnitude response (C, K, P)
10. discuss the differences between FIR and IIR digital filters (C, K)
11. design and test digital audio filters using a computer-aided approach (C, K, P)
12. discuss the techniques used for common audio effects (C, K)
In addition, students will have demonstrated the following professional and transferable skills:
• Programming skills (T, P)
• Problem solving (T)
• Laboratory skills (T, P)
• Group work skills (T)
Key: C-Cognitive/Analytical; K-Subject Knowledge; T-Transferable Skills; P- Professional/ Practical skills
The following is an indication of the likely topics to be covered:
• Introduction to semiconductors, the PN junction, diodes, diode applications, rectification, power supply design.
• The Bipolar Junction Transistor, construction, basic operation, use as an amplifier, use as a switch.
• Bias circuits, small signal amplifier operation, power amplifiers.
• Operational amplifiers, the ideal/non-ideal op-amp. Frequency response, stability and compensation.
• Basic op-amp circuits, adders, differentiators, integrators, comparators, active filters.
• Basic audio circuit design.
• Circuit diagrams and schematic reading. Practical electronics skills.
• Component and system level fault finding.
• Introduction to audio test equipment procedures.
• Electronic circuit construction, familiarisation with electronic components.
• The use of electronics test and measurement equipment.
• The Fourier transform.
• Convolution of two signals.
• Linear time invariant systems, impulse responses, transfer functions and Bode plots.
• The z-transform.
• FIR and IIR digital filters.
• Designing digital filters.
• Common audio effects.
Methods of Teaching/Learning
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 1-7).
• Audio Signal Processing Coursework – two signal processing assignments consisting of mathematical problems (addresses learning outcomes 8-12).
• 2hr exam – Written paper given under exam conditions (addresses learning outcomes 1-4 & 10-12).
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.
Verbal feedback will be provided in laboratory experiments. Written feedback will be given on the coursework assignments.
