Linear and Non-linear Approaches to Decomposition of human Body Pressure Signals
Report, 2009

Pressure signals, collected from a human body, include responses to different excitations such as respiratory and circulatory mechanisms. In a frequency decomposition of pressure signals, this may be an important piece of information to be incorporated into the procedure. In this paper an alternative parametric approach to frequency decomposition of pressure signals is presented. The decomposition scheme employs a harmonic model based on a Volterra series representation of a non-linear system. Both linear and non-linear strategies to estimate the parameters are applied and discussed.
