000002601 520__ $$aSpectroscopic binaries are fundamental sources of precise basic stellar  parameters. Composite spectra of multiple systems are used to determine  orbital parameters, and more recently to reconstruct component spectra.  Techniques used to obtain these goals include measurement of positions  of single spectral lines, cross-correlation using template spectra or  hardware masks, two-dimensional cross-correlation, determination of  broadening functions, subtraction of a template for the primary  component, Doppler tomography, spectral separation and spectral  disentangling. An overview of these techniques will be given pointing  out relations between them, basic limitations, strengths and, when  appropriate, implications for the observing strategy. The second part of the talk will be devoted to a more detailed discussion of spectral  separation and disentangling techniques using either the Fourier  components of the composite spectra or their representation in velocity  (logarithmic wavelength) space, with the aim to give the potential user  insight in equivalence and practical differences between different  approaches. An evaluation of the risks due to near-singularity of the  involved equations and due to bias in the observations is made in the  case of spectral separation of binary stars.
