摘要：

FILTRAN is an operational FORTRAN IV program that calculates one-dimensional Fast Fourier Transforms using the algorithm of Good as modified by Cooley-Tukey and Gentleman-Sande. Options permit selection of time or distance to frequency and then inverse transforms. Input data may be cards, tape, or disk-files and output includes plots on line printer, logical units, or Calcomp Plotter. The program is useful for frequency analysis of many forms of segmented digital data. Filtering and such operations as optimally discriminating, interpolating additional values, and stretching of their data sets. It is versatile, easy to use, and without many of the data restrictions of other Fourier routines. © 1979.
