What is "x !"? What's it mean? "x!" means x factorial. What does "x ==1" mean? When a writer uses non-standard notation, it just torments his readers.

Half sinc IIR?

That's, if not standard, is at least common enough to make my guess seem likely.

To paraphrase > a post from Jerry (years ago), "I understood > what I meant, why didn't you?"Well, it is standard notation--standard C. Admittedly, not standard math though.
