Analysis of transient using homomorphic deconvolution technique

Transient multiexponential signals with real decay constants occurs in different areas of science and technology. Such signals arise in deep-level transient spectroscopy, fluorescence decay analysis, NMR relaxation data, etc. Due to their nonorthogonality, their analysis has proved difficult usi...
