On the representation of signals by basis kernels with product argument
Sorin Cohn-Sfetcu, Michael R. Smith, S.T. Nichols · Proceedings of the IEEE · 1975
This letter discusses a fast digital technique for decomposing signals which are linear superpositions of components having the same form but different widths. This technique, based on the work of Titschmarsh, is a generalization of a method used by Gardner et al. to analyze multicomponent exponential decays.
