Abstract

It has been suggested that convolution functions other than Ernst's optimal matched filter may be efficacious for resolution enhancement of NMR spectra. For the purposes of comparison, the possible line distortions and signal-to-noise and resolution enhancement ratios in the Ernst filter are explicitly derived. The general limitation inherent in the digital transformation on the minimum linewidth obtainable by any convolution filter is also derived.
