1. Instantaneous Biomedical Signal Analysis: Theory, Advances and Applications
Speaker: Sri Krishnan, PhD, PEng
Position/Affiliation: Canada Research Chair in Biomedical Signal Analysis,
Professor, Department of Electrical and Computer Eng.
Ryerson University, Toronto, Canada
Tutorial Abstract:
A signal can be considered to be stationary if its statistical characteristics do not change with time. However, most real world signals are non-stationary and have highly complex time-varying characteristics. Common signal analysis and modelling techniques and classical time-frequency distributions (TFDs) do not readily provide the time-varying signal features of interest. There are several limitations with the classical parametric signal representations, and these problems could be obviated by using true nonstationary signal analysis tools such as adaptive signal representations and adaptive TFDs. Construction of proper adaptive TFDs and the methodologies for extracting instantaneous and quantifiable signal parameters will be discussed in detail. The extraction and monitoring of spectral and related parameters with time is of immense use in a variety of signal analysis applications such as RADAR, biomedical, and geophysics. The application of the extraction and classification of complex instantaneous signal parameters with respect to three real world biomedical signals (cardiac electrograms, pathological speech signals and knee vibration signals) will be discussed in detail.
