Signal and Noise

Class lecture on signal and noise by University of Geneva

Signal to noise formulations in CCD cameras

Review of S-to-N characteristics in the in photographic images

Alkemade seminal paper on Signal to Noise "A review and tutorial discussion of noise and signal-to-noise ratios in analytical spectrometry-I. Fundamental principles of signal-to-noise ratios*"

Near-infrared spectroscopy book

An atlas for NIR spectra by functional groups Practical Guide and Spectral Atlas for Interpretive Near-Infrared Spectroscopy, Sercond Edition Spectroscopy, Second Edition

Some easy Fourier Transform explanation

I found a good 'a pied' tutorial on FT.

Analytical Spectroscopy

Finally i found some good slides for the Analytical Spectroscopy lecture notes (based on the Spectrochemical Analysis book)

A set of slides for UV-Vis
