Smoothing

Description

Various methods of smoothing can be applied to improve the signal-to-noise ratio. For instance, data points recorded over time [s] or over a range of wavelengths [nm] can be smoothed by averaging n data points per interval. Then the average of the n points per smoothing interval can be taken for each successively recorded data point across the time range or range of the spectrum to give a n-point moving average smoothing. This method decreases the noise of the signal, but clearly reduces the time or wavelength resolution. More advanced methods of smoothing are applied to retain a higher time resolution or wavelength resolution.

-|description=The [[signal-to-noise ratio]] can be improved by spectral ‘’’smoothing’’’. This is achieved by averaging several adjacent data points across the recorded spectrum. For example, if the instrument recorded 5 data points per nm, the average of the 5 points can be taken for each successive nm across the range of the spectrum to give a 5-point smoothing. This method clearly reduces the wavelength [[resolution]].
+|description=Various methods of '''smoothing''' can be applied to improve the [[signal-to-noise ratio]]. For instance, data points recorded over time [s] or over a range of wavelengths [nm] can be smoothed by averaging ''n'' data points per interval. Then the average of the ''n'' points per smoothing interval can be taken for each successively recorded data point across the time range or range of the spectrum to give a ''n''-point [[moving average]] smoothing. This method decreases the [[noise]] of the signal, but clearly reduces the time or wavelength [[resolution]]. More advanced methods of smoothing are applied to retain a higher [[time resolution]] or wavelength resolution.
