The Inverse Gaussian Pulse in the Experimental Determination of Linear System Green's Functions,
Abstract
This article presents a new time domain deconvolution method for determining the impulse response of linear time invariant systems. The method is based on the use of the one-sided, causal, inverse Gaussian pulse as an approximation to the Dirac delta-function. Deconvolution of that kernel is equivalent to an inverse heat conduction problem. The method is particularly useful in cases where the Green's function for the linear system has singularities such as jumps, cusps, spikes, and the like. Computational reconstructions of singularities, from smooth synthetic data, are presented in the context of Acoustic Emission Green's functions. (Author)
