Noise Reduction via Factor Analysis in FT-IR Spectra

Volume 36, Number 5 (Oct. 1982) Page 535-539

Gillette, P.C.; Koenig, J.L.

The application of factor analysis to reduce random noise in FT-IR spectra is described. By utilizing the total information content of all the spectra, it is possible to reduce the amount of random noise present in individual spectrum.
