Remez exchange algorithm

Calculating FIR filter coefficients.

The files are:

    Name           Desc
    ----           ----
    README         You are reading it
    remez.c        Source code
    Makefile       For Unix/Linux
    example        Short description
    lowpass        Sample lowpass filter parameters
    hilbert        Sample Hilbert transform parameters
    bandpass       Sample bandpass filter parameters
    highpass       Sample highpass filter parameters
    differen       Sample differentiator parameters
    plotit         Plot resulting response using gnuplot

The programs may be run interactively, or via a pre-prepared parameter
list. A sample of the latter method is:

	remez <lowpass >lowpass.doc

An FFT will always be performed as a control, showing the actual
frequency response achieved.

An simple example of how to make a simple FIR filter may be found in
the file EXAMPLE.

For a guide to understanding FIR-filter and related issues, the
following book is recommended:

	Lawrence R. Rabiner - Bernard Gold

	Theory and Application of DIgital Signal Processing

Admittedly, this is not the most friendly user interface that
you might have encountered, but it does the job.

Please let me know about bugs, comments and such.
