Milieux poreux
The NMR spectra of porous materials are characterised by broad spectral lines, often due to intrinsic inhomogeneity of their magnetic susceptibility. Another recurrent feature of the spectra is them being a band-limited function. Herein we show that time-domain signals of those systems can be modelled precisely and effectively by finite cardinal series. Such modelling can, in turn, be used for restoration of signals should they be damaged or for design of a digital low-pass filter, which stay applicable even when experimentally acquired signals are truncated.
