There is a second edition out of this book:
	"Digital Signal Analysis"
	S. D. Stearns and D. R. Hush
	Prentice Hall 1990
	ISBN 0-13-213117-X

It comes with a DOS floppy with Fortran source code and includes some simple
design routines.

You might also check out "Digital Filters" by Tom Parks (sorry, I don't
have the book here).  This is a comprehensive look at designing filters
and includes Fortran code (but no disk).

There are several commercial SW packages available, but they are rather
expensive.
