Abstract

While the techniques of Fourier analysis and signal processing lend themselves to the development of computer programs for data reduction, relatively few programs offer a full complement of algorithms specialized to spectroscopy. Programs for interactive Fourier analysis should provide an environment in which various techniques can be compared and in which data can be displayed and manipulated in both Fourier domains. The decomp spectral decomposition program is designed for the reduction of Fourier transform spectra and focuses on interactive graphic display and Fourier analysis of data. For experiments that require the maximum achievable accuracy or must coax a modicum of signal from noise the DECOMP package offers something more than black-box spectrum analysis. Techniques of Fourier analysis and signal processing are demonstrated, and an IBM PC-compatible computer is available for hands-on demonstrations.
