Description
The concepts of linear signals and systems analysis, developed primarily by electrical engineers, are of great importance to understanding many aspects of auditory physiology, speech production, speech perception, speech acoustics, and the processing of physiological neuroscience measures such as EEG, fMRI, fNIRS and others. However, it is very difficult for the many people working in the speech and hearing sciences who come from a background in the arts or humanities (or even psychology) to master these essential technical underpinnings. The aim of this module is to provide a thorough introduction to the concepts of signals and systems analysis that play a role in the speech and hearing sciences for a student without extensive prior mathematical training. Emphasis is on the conceptual underpinnings of the area, through a primarily graphical approach, rather than one based primarily on mathematical formulae.
The course will be presented as a series of 10 lectures and laboratory sessions. The lectures will introduce core topics, supported by readings in an associated textbook. The laboratory sessions will provide 鈥渉ands-on鈥 experience working with digital signals and systems.
Indicative Topics
- Signals: periodicity/aperiodicity; simple vs. complex
- Systems: Linearity; time-invariance
- Frequency response of systems
- Frequency representation of signals (spectra)
- Signals through systems in the frequency domain
- Impulse responses and convolution
- Time/bandwidth trading
- Practical methods of spectral analysis 鈥 the spectrogram
- Digital signals and systems
