S.P.E.C.T.R.U.M. (Signal Processing for Experimental Chemistry Teaching and Research/ University of Maryland)
series data (y values at equally-spaced x intervals), such as
spectra, chromatograms, electrochemical signals, etc. The program
enhances the information content of instrument signals, for
example by reducing noise, improving resolution, compensating for
instrumental artifacts, testing hypotheses, and decomposing a
complex signal into its component parts. Includes reference manual
and tutorial. For Macintosh or Windows PC with Mac emulator.
