Computer Interface and Digital Sweep for an NMR Spectrometer

Abstract

The powerful technique of using a small digital computer to enhance the signal to noise ratios of weak NMR signals is well known. In short, the NMR spectrometer-computer interface consists of an integrating type analog to digital converter to digitize the spectrometers output, a digital to analog converter to display the collected spectra, and a digital sweep system to control the frequency or field of the NMR spectrometer. The latter also serves as the timing element used to read the analog to digital converter and to advance the channel of a multichannel analyzer program.
