Abstract: In this paper, we have introduced some general principles and methods for noise elimination and data compression of 2D NMR spectral data, including phase-sensitive mode, power mode and absolute mode spectra. The idea was originated from the necessity of alleviating some problems of NMR spectrometer, such as user-time tramming and limit storage device. Some technicalities were notified combined with a brief description of the implementation of those methods on Sun SPARC workstation. To show the applicability and feasibility of the methods, we present an experiment instance which gain a 10:1 compression ratio with respect to the original spectral data.
