This module is not approved as a discovery module
Objectives
This module introduces the principles of signals and signal analysis in the context of audio systems, and develops knowledge and understanding of signal conditioning, detection and quantisation.Students will also be introduced to digital signal processing techniques relevant to audio applications.
Learning outcomes
On completion of this module students should be able to:
1. Discuss the fundamental properties of signals and interpret time domain and frequency domain representation of signals.
2. Perform simple calculations on a range of signal properties.
3. Explain the principles and applications of analogue to digital conversion (ADC) and calculate the requirements for typical ADC systems.
4. Select and design a range of analogue circuits suitable for audio signal conditioning, including amplifiers, buffers and filters.
5. Explain the fundamental components of digital signal processing (DSP).
6. Apply DSP functions on a microcontroller to implement a range of signal processing tasks for audio applications.
Skills outcomes
Develops a critical judgement of how analogue and digital signal processing can affect audio quality.
Syllabus
Topics may include, but are not limited to:
Properties of signals, waveform, amplitude, frequency, phase, power, harmonics.
Modulation and superposition.
Analogue to Digital Conversion, including sampling, effects of aliasing, bit depth/quantisation, over/undersampling and interpolation.
Signal Conditioning, including circuit design and signal processing components, op-amps and filters, including active filters
Fundamentals of Digital Signal Processing (DSP), time domain/frequency domain representation, Fourier analysis for practical applications, digital filters, real-time DSP.

Private study
Students are expected to use private study time to consolidate their understanding of course materials, to undertake preparatory work for seminars, workshops, tutorials, examples classes and practical classes, and also to prepare for in-course and summative assessments.Opportunities for Formative Feedback
Students studying ELEC modules will receive formative feedback in a variety of ways, including the use of self-test quizzes on Minerva, practice questions/worked examples and (where appropriate) through verbal interaction with teaching staff and/or post-graduate demonstrators.Methods of assessment
