The maximum entropy method and fourier transformation compared
Journal of Magnetic Resonance (1969) 92:2 (1991) 276-292
Abstract:
The relationship between NMR spectra obtained by the maximum entropy method and by conventional processing (Fourier transformation) is explored. In certain circumstances, the maximum entropy reconstruction is simply a nonlinearly amplified form of the Fourier transform spectrum and is therefore essentially worthless. More complex and interesting behavior is found under conditions more likely to be met in practice. Using simple examples, it is argued that a maximum entropy reconstruction can reveal information that could not be obtained from a single Fourier transform spectrum. © 1991.The maximum entropy method.

Abstract:
It has often been asserted that the maximum entropy method can simultaneously suppress noise and enhance resolution in NMR spectra. We examine this claim using a Monte Carlo method to determine the accuracy and precision of line heights and integrals in spectra obtained by various forms of the maximum entropy method. It is shown that maximum entropy processing with lineshape deconvolution produces results that are roughly comparable to least-squares fitting of a model lineshape to the conventional Fourier transform spectrum. © 1991.Drive-noise tolerant optical switching
