Spectral disentangling allows us to reconstruct the contribution of multiple stars to a composite spectrum. Different algorithms have been proposed, which fall in two categories: algorithms operating on the Fourier components of the spectra and algorithms operating on the velocity bins (logarithm of wavelength). Almost all applications use the former algorithms because of public availability of software code and the computing time involved. Nevertheless, the simultaneous use of both techniques would give a better insight in the error budget, since each algorithms is sensitive in a different way to uncertainties in the input data and the options available to assign weights to the input data are different. We will discuss the application of both techniques to a triple system, consisting of a dominant stationary third component dominating the composite spectrum and a close binary with one component much fainter than the other. Several spectral regions are selected, some of which contain telluric lines. When necessary for a better understanding, also simpler artificial spectra are analysed by both techniques.
