(except for a delay, wich is symmetric and anti-symmetric)

We're on a bit of a slippery slope (in my opinion) since these
terms aren't fully defined, but in the case of the terminology
"even symmetric" and "odd symmetric" that I've learned, an
odd-symmetric function is necessarily 0 at t=0.

How about [-1 2 1]? Or [0 1 0]?

Are either of these supposed to be odd symmetric?

Both of them are odd symmetric, and therefore linear-phase FIR filters.
