title: Nonlinear methods in spectral analysis of NMR signals from living systems.
abstract: Two autoregressive procedures, namely Burg's maximum entropy method and Prony's method, have been applied to the processing of 31P NMR signals (free induction decays) of human cells. A comparison of the main advantages obtained by using these methods in the field of the NMR spectral analysis of signals from living samples is here illustrated. Improvements in sensitivity and resolution are obtained with respect to Fourier transform method by using only very few data points.
