I have done some playing around with FIR filters for various purposes, and
always find something peculiar.  FIR filters always have odd tap counts.
Why is that?  I have looked in various DSP books, but can find no hint as
to why that fact is true.  The books I have looked in, however, always use
odd tap counts.  Can somebody give me a good, clear explaination?  I'm more
interested in a real explaination rather than pointers to books or
articles, but will try to find the articles if sited.
