Parameter Extraction in Multi Step Exponential Signal

Domenico Luca Carnì, Domenico Grimaldi, Linus Michaeli, Jan Saliga
Abstract:
Multi-exponential function is used to model phenomenon or signal in several applications. The parameter extraction of each exponential is based on the assumption that no constant component is part of the signal. In the paper the superposition of exponential signals and step signals starting in different time instants is taken into consideration, and a procedure based on windowing is pointed out to estimate the parameters of each exponential function in addition to the delay of each step. Numerical tests asses the correctness of the procedure.
