NMR Instruments - The Digital Console

Once data has been collected by the magnet, it is sent to the digital console as a FID. The digital console determines the frequency and intensity of each component wave of the FID, by performing a Fourier Transform of the data. These frequencies and intensities make up the peaks of an NMR spectrum. The digital console then performs other manipulations of the data, such as zero-filling and apodization. These calculations help to make the spectrum as detailed as possible and they eliminate imperfections caused by data loss when the FID is sent from the magnet to the digital console.
