Abstract

An apparatus, software, and method for segregating out background signals from a signal of interest comprising sampling a signal that includes the background signals over one or more periods of time, forming a matrix from results of the sampling, calculating a matrix of basis functions via a singular value decomposition of the matrix from the forming operation, and determining a set of basis functions to employ to segregate out background signals. Also a corresponding wavelength modulation spectroscopy apparatus, software, and method.
