The FORTRAN source code for a general bandpass/differentiating/Hilbert
transform FIR filter can be found in Lawrence R. Rabiner & Bernard Gold
(1975), Theory and Application of Digital Signal Processing, Prentice-
Hall, Englewood Cliffs, NJ, USA, pp. 187-204.  I seem to recall that the
IEEE brought out a tape/diskette some years ago with DSP s/w, but I don't
have any details handy.  You might check with the IEEE Transactions on
ASSP.
