[sci.math] need info : math in dig. processing

Hello.

I am looking for a book that I used last year from my univ. library,
but can no longer find, and I need it again.

The book was a really goood explanation of the way filters, or digital
signal processing worrked mathematically. The title of hte book was
something like 

Filter Theory for Mathematicians
or
Digital Signal Processing for mathematicians
or 
SOmething like that. 


What I need is a book written for mathematicians that explains
(without getting too complicated and w/out getting into appllications
too much) the math of filters and digital processing...



Please help me. I have ravaged (yeah, that's right :-) ) all the catalogs
and computer catalogs for this book that I know is out there, but
whose title or authour I cannot remember.The reference desk people weren't
much help either...

Another clue I have is that I remember the authour writing in the
foreword that this was a book for mathematicians who did not know the
electronics...


Thank You  very much.
